-The easiest way to read this source is to put something like the
-following in your @file{~/.gnus.el} file:
-
-@lisp
-(setq gnus-secondary-select-methods
- '((nnslashdot "")))
-@end lisp
-
-This will make Gnus query the @code{nnslashdot} back end for new comments
-and groups. The @kbd{F} command will subscribe each new news article as
-a new Gnus group, and you can read the comments by entering these
-groups. (Note that the default subscription method is to subscribe new
-groups as zombies. Other methods are available (@pxref{Subscription
-Methods}).
-
-If you want to remove an old @code{nnslashdot} group, the @kbd{G DEL}
-command is the most handy tool (@pxref{Foreign Groups}).
-
-When following up to @code{nnslashdot} comments (or posting new
-comments), some light @acronym{HTML}izations will be performed. In
-particular, text quoted with @samp{> } will be quoted with
-@samp{blockquote} instead, and signatures will have @samp{br} added to
-the end of each line. Other than that, you can just write @acronym{HTML}
-directly into the message buffer. Note that Slashdot filters out some
-@acronym{HTML} forms.
-
-The following variables can be altered to change its behavior:
-
-@table @code
-@item nnslashdot-threaded
-Whether @code{nnslashdot} should display threaded groups or not. The
-default is @code{t}. To be able to display threads, @code{nnslashdot}
-has to retrieve absolutely all comments in a group upon entry. If a
-threaded display is not required, @code{nnslashdot} will only retrieve
-the comments that are actually wanted by the user. Threading is nicer,
-but much, much slower than unthreaded.
-
-@item nnslashdot-login-name
-@vindex nnslashdot-login-name
-The login name to use when posting.
-
-@item nnslashdot-password
-@vindex nnslashdot-password
-The password to use when posting.
-
-@item nnslashdot-directory
-@vindex nnslashdot-directory
-Where @code{nnslashdot} will store its files. The default is
-@file{~/News/slashdot/}.
-
-@item nnslashdot-active-url
-@vindex nnslashdot-active-url
-The @acronym{URL} format string that will be used to fetch the
-information on news articles and comments. The default is@*
-@samp{http://slashdot.org/search.pl?section=&min=%d}.
-
-@item nnslashdot-comments-url
-@vindex nnslashdot-comments-url
-The @acronym{URL} format string that will be used to fetch comments.
-
-@item nnslashdot-article-url
-@vindex nnslashdot-article-url
-The @acronym{URL} format string that will be used to fetch the news
-article. The default is
-@samp{http://slashdot.org/article.pl?sid=%s&mode=nocomment}.
-

-The score threshold. The default is -1.
-
-@item nnslashdot-group-number

-@cindex @acronym{IMAP}
-
-@acronym{IMAP} is a network protocol for reading mail (or news, or @dots{}),
-think of it as a modernized @acronym{NNTP}. Connecting to a @acronym{IMAP}
-server is much similar to connecting to a news server, you just
-specify the network address of the server.
-
-@acronym{IMAP} has two properties. First, @acronym{IMAP} can do
-everything that @acronym{POP} can, it can hence be viewed as a
-@acronym{POP++}. Secondly, @acronym{IMAP} is a mail storage protocol,
-similar to @acronym{NNTP} being a news storage protocol---however,
-@acronym{IMAP} offers more features than @acronym{NNTP} because news
-is more or less read-only whereas mail is read-write.
-
-If you want to use @acronym{IMAP} as a @acronym{POP++}, use an imap
-entry in @code{mail-sources}. With this, Gnus will fetch mails from
-the @acronym{IMAP} server and store them on the local disk. This is
-not the usage described in this section---@xref{Mail Sources}.
-
-If you want to use @acronym{IMAP} as a mail storage protocol, use an nnimap
-entry in @code{gnus-secondary-select-methods}. With this, Gnus will
-manipulate mails stored on the @acronym{IMAP} server. This is the kind of
-usage explained in this section.
-
-A server configuration in @file{~/.gnus.el} with a few @acronym{IMAP}
-servers might look something like the following. (Note that for
-@acronym{TLS}/@acronym{SSL}, you need external programs and libraries,
-see below.)
-
-@lisp
-(setq gnus-secondary-select-methods
- '((nnimap "simpleserver") ; @r{no special configuration}
- ; @r{perhaps a ssh port forwarded server:}
- (nnimap "dolk"
- (nnimap-address "localhost")
- (nnimap-server-port 1430))
- ; @r{a UW server running on localhost}
- (nnimap "barbar"
- (nnimap-server-port 143)
- (nnimap-address "localhost")
- (nnimap-list-pattern ("INBOX" "mail/*")))
- ; @r{anonymous public cyrus server:}
- (nnimap "cyrus.andrew.cmu.edu"
- (nnimap-authenticator anonymous)
- (nnimap-list-pattern "archive.*")
- (nnimap-stream network))
- ; @r{a ssl server on a non-standard port:}
- (nnimap "vic20"
- (nnimap-address "vic20.somewhere.com")
- (nnimap-server-port 9930)
- (nnimap-stream ssl))))
-@end lisp
-
-After defining the new server, you can subscribe to groups on the
-server using normal Gnus commands such as @kbd{U} in the Group Buffer
-(@pxref{Subscription Commands}) or via the Server Buffer
-(@pxref{Server Buffer}).
-
-The following variables can be used to create a virtual @code{nnimap}
-server:
-
-@table @code
-
-@item nnimap-address
-@vindex nnimap-address
-
-The address of the remote @acronym{IMAP} server. Defaults to the virtual
-server name if not specified.
-
-@item nnimap-server-port
-@vindex nnimap-server-port
-Port on server to contact. Defaults to port 143, or 993 for @acronym{TLS}/@acronym{SSL}.
-
-Note that this should be an integer, example server specification:
-
-@lisp
-(nnimap "mail.server.com"
- (nnimap-server-port 4711))
-@end lisp
-
-@item nnimap-list-pattern
-@vindex nnimap-list-pattern
-String or list of strings of mailboxes to limit available groups to.
-This is used when the server has very many mailboxes and you're only
-interested in a few---some servers export your home directory via
-@acronym{IMAP}, you'll probably want to limit the mailboxes to those in
-@file{~/Mail/*} then.
-
-The string can also be a cons of REFERENCE and the string as above, what
-REFERENCE is used for is server specific, but on the University of
-Washington server it's a directory that will be concatenated with the
-mailbox.
-
-Example server specification:
-
-@lisp
-(nnimap "mail.server.com"
- (nnimap-list-pattern ("INBOX" "Mail/*" "alt.sex.*"
- ("~friend/Mail/" . "list/*"))))
-@end lisp
-
-@item nnimap-stream
-@vindex nnimap-stream
-The type of stream used to connect to your server. By default, nnimap
-will detect and automatically use all of the below, with the exception
-of @acronym{TLS}/@acronym{SSL}. (@acronym{IMAP} over
-@acronym{TLS}/@acronym{SSL} is being replaced by STARTTLS, which can
-be automatically detected, but it's not widely deployed yet.)
-
-Example server specification:
-
-@lisp
-(nnimap "mail.server.com"

-
-@vindex imap-kerberos4-program
-The @samp{imtest} program is shipped with Cyrus IMAPD. If you're
-using @samp{imtest} from Cyrus IMAPD < 2.0.14 (which includes version
-1.5.x and 1.6.x) you need to frob @code{imap-process-connection-type}
-to make @code{imap.el} use a pty instead of a pipe when communicating
-with @samp{imtest}. You will then suffer from a line length
-restrictions on @acronym{IMAP} commands, which might make Gnus seem to hang
-indefinitely if you have many articles in a mailbox. The variable
-@code{imap-kerberos4-program} contain parameters to pass to the imtest
-program.
-
-For @acronym{TLS} connection, the @code{gnutls-cli} program from GNUTLS is
-needed. It is available from
-@uref{http://www.gnu.org/software/gnutls/}.
-
-@vindex imap-gssapi-program
-This parameter specifies a list of command lines that invoke a GSSAPI
-authenticated @acronym{IMAP} stream in a subshell. They are tried
-sequentially until a connection is made, or the list has been
-exhausted. By default, @samp{gsasl} from GNU SASL, available from
-@uref{http://www.gnu.org/software/gsasl/}, and the @samp{imtest}
-program from Cyrus IMAPD (see @code{imap-kerberos4-program}), are
-tried.
-
-@vindex imap-ssl-program
-For @acronym{SSL} connections, the OpenSSL program is available from
-@uref{http://www.openssl.org/}. OpenSSL was formerly known as SSLeay,
-and nnimap support it too---although the most recent versions of
-SSLeay, 0.9.x, are known to have serious bugs making it
-useless. Earlier versions, especially 0.8.x, of SSLeay are known to
-work. The variable @code{imap-ssl-program} contain parameters to pass
-to OpenSSL/SSLeay.
-
-@vindex imap-shell-program
-@vindex imap-shell-host
-For @acronym{IMAP} connections using the @code{shell} stream, the
-variable @code{imap-shell-program} specify what program to call. Make
-sure nothing is interfering with the output of the program, e.g., don't
-forget to redirect the error output to the void.
-
-@item nnimap-authenticator
-@vindex nnimap-authenticator
-
-The authenticator used to connect to the server. By default, nnimap
-will use the most secure authenticator your server is capable of.
-
-Example server specification:
-
-@lisp
-(nnimap "mail.server.com"

-@item nnimap-expunge-on-close
-@cindex expunging
-@vindex nnimap-expunge-on-close
-Unlike Parmenides the @acronym{IMAP} designers have decided things that
-don't exist actually do exist. More specifically, @acronym{IMAP} has
-this concept of marking articles @code{Deleted} which doesn't actually
-delete them, and this (marking them @code{Deleted}, that is) is what
-nnimap does when you delete an article in Gnus (with @kbd{B DEL} or
-similar).
-
-Since the articles aren't really removed when we mark them with the
-@code{Deleted} flag we'll need a way to actually delete them. Feel like
-running in circles yet?
-
-Traditionally, nnimap has removed all articles marked as @code{Deleted}
-when closing a mailbox but this is now configurable by this server
-variable.
-
-The possible options are:
-
-@table @code
-
-@item always
-The default behavior, delete all articles marked as ``Deleted'' when
-closing a mailbox.
-@item never
-Never actually delete articles. Currently there is no way of showing
-the articles marked for deletion in nnimap, but other @acronym{IMAP} clients
-may allow you to do this. If you ever want to run the EXPUNGE command
-manually, @xref{Expunging mailboxes}.
-@item ask
-When closing mailboxes, nnimap will ask if you wish to expunge deleted
-articles or not.
-
-@end table
-
-@item nnimap-importantize-dormant
-@vindex nnimap-importantize-dormant
-
-If non-@code{nil} (the default), marks dormant articles as ticked (as
-well), for other @acronym{IMAP} clients. Within Gnus, dormant articles will
-naturally still (only) be marked as dormant. This is to make dormant
-articles stand out, just like ticked articles, in other @acronym{IMAP}
-clients. (In other words, Gnus has two ``Tick'' marks and @acronym{IMAP}
-has only one.)
-
-Probably the only reason for frobbing this would be if you're trying
-enable per-user persistent dormant flags, using something like:
-
-@lisp
-(setcdr (assq 'dormant nnimap-mark-to-flag-alist)
- (format "gnus-dormant-%s" (user-login-name)))
-(setcdr (assq 'dormant nnimap-mark-to-predicate-alist)
- (format "KEYWORD gnus-dormant-%s" (user-login-name)))
-@end lisp
-
-In this case, you would not want the per-user dormant flag showing up
-as ticked for other users.
-
-@item nnimap-expunge-search-string
-@cindex expunging
-@vindex nnimap-expunge-search-string
-@cindex expiring @acronym{IMAP} mail
-
-This variable contain the @acronym{IMAP} search command sent to server when
-searching for articles eligible for expiring. The default is
-@code{"UID %s NOT SINCE %s"}, where the first @code{%s} is replaced by
-UID set and the second @code{%s} is replaced by a date.
-
-Probably the only useful value to change this to is
-@code{"UID %s NOT SENTSINCE %s"}, which makes nnimap use the Date: in
-messages instead of the internal article date. See section 6.4.4 of
-RFC 2060 for more information on valid strings.
-
-However, if @code{nnimap-search-uids-not-since-is-evil}
-is true, this variable has no effect since the search logic
-is reversed, as described below.
-
-@item nnimap-authinfo-file
-@vindex nnimap-authinfo-file
-
-A file containing credentials used to log in on servers. The format is
-(almost) the same as the @code{ftp} @file{~/.netrc} file. See the
-variable @code{nntp-authinfo-file} for exact syntax; also see
-@ref{NNTP}. An example of an .authinfo line for an IMAP server, is:
-
-@example
-machine students.uio.no login larsi password geheimnis port imap
-@end example
-
-Note that it should be @code{port imap}, or @code{port 143}, if you
-use a @code{nnimap-stream} of @code{tls} or @code{ssl}, even if the
-actual port number used is port 993 for secured IMAP. For
-convenience, Gnus will accept @code{port imaps} as a synonym of
-@code{port imap}.
-
-@item nnimap-need-unselect-to-notice-new-mail
-@vindex nnimap-need-unselect-to-notice-new-mail
-
-Unselect mailboxes before looking for new mail in them. Some servers
-seem to need this under some circumstances; it was reported that
-Courier 1.7.1 did.
-
-@item nnimap-nov-is-evil
-@vindex nnimap-nov-is-evil
-@cindex Courier @acronym{IMAP} server
-@cindex @acronym{NOV}
-
-Never generate or use a local @acronym{NOV} database. Defaults to the
-value of @code{gnus-agent}.
-
-Using a @acronym{NOV} database usually makes header fetching much
-faster, but it uses the @code{UID SEARCH UID} command, which is very
-slow on some servers (notably some versions of Courier). Since the Gnus
-Agent caches the information in the @acronym{NOV} database without using
-the slow command, this variable defaults to true if the Agent is in use,
-and false otherwise.
-
-@item nnimap-search-uids-not-since-is-evil
-@vindex nnimap-search-uids-not-since-is-evil
-@cindex Courier @acronym{IMAP} server
-@cindex expiring @acronym{IMAP} mail
-
-Avoid the @code{UID SEARCH UID @var{message numbers} NOT SINCE
-@var{date}} command, which is slow on some @acronym{IMAP} servers
-(notably, some versions of Courier). Instead, use @code{UID SEARCH SINCE
-@var{date}} and prune the list of expirable articles within Gnus.
-
-When Gnus expires your mail (@pxref{Expiring Mail}), it starts with a
-list of expirable articles and asks the IMAP server questions like ``Of
-these articles, which ones are older than a week?'' While this seems
-like a perfectly reasonable question, some IMAP servers take a long time
-to answer it, since they seemingly go looking into every old article to
-see if it is one of the expirable ones. Curiously, the question ``Of
-@emph{all} articles, which ones are newer than a week?'' seems to be
-much faster to answer, so setting this variable causes Gnus to ask this
-question and figure out the answer to the real question itself.
-
-This problem can really sneak up on you: when you first configure Gnus,
-everything works fine, but once you accumulate a couple thousand
-messages, you start cursing Gnus for being so slow. On the other hand,
-if you get a lot of email within a week, setting this variable will
-cause a lot of network traffic between Gnus and the IMAP server.
-
-@item nnimap-logout-timeout
-@vindex nnimap-logout-timeout
-
-There is a case where a connection to a @acronym{IMAP} server is unable
-to close, when connecting to the server via a certain kind of network,
-e.g. @acronym{VPN}. In that case, it will be observed that a connection
-between Emacs and the local network looks alive even if the server has
-closed a connection for some reason (typically, a timeout).
-Consequently, Emacs continues waiting for a response from the server for
-the @code{LOGOUT} command that Emacs sent, or hangs in other words. If
-you are in such a network, setting this variable to a number of seconds
-will be helpful. If it is set, a hung connection will be closed
-forcibly, after this number of seconds from the time Emacs sends the
-@code{LOGOUT} command. It should not be too small value but too large
-value will be inconvenient too. Perhaps the value 1.0 will be a good
-candidate but it might be worth trying some other values.

-@cindex splitting imap mail
-
-Splitting is something Gnus users have loved and used for years, and now
-the rest of the world is catching up. Yeah, dream on, not many
-@acronym{IMAP} servers have server side splitting and those that have
-splitting seem to use some non-standard protocol. This means that
-@acronym{IMAP} support for Gnus has to do its own splitting.
-
-And it does.
-
-(Incidentally, people seem to have been dreaming on, and Sieve has
-gaining a market share and is supported by several IMAP servers.
-Fortunately, Gnus support it too, @xref{Sieve Commands}.)
-
-Here are the variables of interest:
-
-@table @code
-
-@item nnimap-split-crosspost
-@cindex splitting, crosspost
-@cindex crosspost
-@vindex nnimap-split-crosspost
-
-If non-@code{nil}, do crossposting if several split methods match the
-mail. If @code{nil}, the first match in @code{nnimap-split-rule}
-found will be used.
-
-Nnmail equivalent: @code{nnmail-crosspost}.
-
-@item nnimap-split-inbox
-@cindex splitting, inbox
-@cindex inbox
-@vindex nnimap-split-inbox
-
-A string or a list of strings that gives the name(s) of @acronym{IMAP}
-mailboxes to split from. Defaults to @code{nil}, which means that
-splitting is disabled!
-
-@lisp
-(setq nnimap-split-inbox
- '("INBOX" ("~/friend/Mail" . "lists/*") "lists.imap"))
-@end lisp
-
-No nnmail equivalent.
-
-@item nnimap-split-rule
-@cindex splitting, rules
-@vindex nnimap-split-rule
-
-New mail found in @code{nnimap-split-inbox} will be split according to
-this variable.
-
-This variable contains a list of lists, where the first element in the
-sublist gives the name of the @acronym{IMAP} mailbox to move articles
-matching the regexp in the second element in the sublist. Got that?
-Neither did I, we need examples.
-
-@lisp
-(setq nnimap-split-rule
- '(("INBOX.nnimap"
- "^Sender: owner-nnimap@@vic20.globalcom.se")
- ("INBOX.junk" "^Subject:.*MAKE MONEY")
- ("INBOX.private" "")))
-@end lisp
-
-This will put all articles from the nnimap mailing list into mailbox
-INBOX.nnimap, all articles containing MAKE MONEY in the Subject: line
-into INBOX.junk and everything else in INBOX.private.
-
-The first string may contain @samp{\\1} forms, like the ones used by
-replace-match to insert sub-expressions from the matched text. For
-instance:
-
-@lisp
-("INBOX.lists.\\1" "^Sender: owner-\\([a-z-]+\\)@@")
-@end lisp
-
-The first element can also be the symbol @code{junk} to indicate that
-matching messages should simply be deleted. Use with care.
-
-The second element can also be a function. In that case, it will be
-called with the first element of the rule as the argument, in a buffer
-containing the headers of the article. It should return a
-non-@code{nil} value if it thinks that the mail belongs in that group.
-
-Nnmail users might recollect that the last regexp had to be empty to
-match all articles (like in the example above). This is not required in
-nnimap. Articles not matching any of the regexps will not be moved out
-of your inbox. (This might affect performance if you keep lots of
-unread articles in your inbox, since the splitting code would go over
-them every time you fetch new mail.)
-
-These rules are processed from the beginning of the alist toward the
-end. The first rule to make a match will ``win'', unless you have
-crossposting enabled. In that case, all matching rules will ``win''.
-
-This variable can also have a function as its value, the function will
-be called with the headers narrowed and should return a group where it
-thinks the article should be split to. See @code{nnimap-split-fancy}.
-
-The splitting code tries to create mailboxes if it needs to.
-
-To allow for different split rules on different virtual servers, and
-even different split rules in different inboxes on the same server,
-the syntax of this variable have been extended along the lines of:
-
-@lisp
-(setq nnimap-split-rule
- '(("my1server" (".*" (("ding" "ding@@gnus.org")
- ("junk" "From:.*Simon"))))
- ("my2server" ("INBOX" nnimap-split-fancy))
- ("my[34]server" (".*" (("private" "To:.*Simon")
- ("junk" my-junk-func))))))
-@end lisp
-
-The virtual server name is in fact a regexp, so that the same rules
-may apply to several servers. In the example, the servers
-@code{my3server} and @code{my4server} both use the same rules.
-Similarly, the inbox string is also a regexp. The actual splitting
-rules are as before, either a function, or a list with group/regexp or
-group/function elements.
-
-Nnmail equivalent: @code{nnmail-split-methods}.
-
-@item nnimap-split-predicate
-@cindex splitting
-@vindex nnimap-split-predicate
-
-Mail matching this predicate in @code{nnimap-split-inbox} will be
-split, it is a string and the default is @samp{UNSEEN UNDELETED}.
-
-This might be useful if you use another @acronym{IMAP} client to read mail in
-your inbox but would like Gnus to split all articles in the inbox
-regardless of readedness. Then you might change this to
-@samp{UNDELETED}.
-
-@item nnimap-split-fancy
-@cindex splitting, fancy
-@findex nnimap-split-fancy
-@vindex nnimap-split-fancy
-
-It's possible to set @code{nnimap-split-rule} to
-@code{nnmail-split-fancy} if you want to use fancy
-splitting. @xref{Fancy Mail Splitting}.
-
-However, to be able to have different fancy split rules for nnmail and
-nnimap back ends you can set @code{nnimap-split-rule} to
-@code{nnimap-split-fancy} and define the nnimap specific fancy split
-rule in @code{nnimap-split-fancy}.
-
-Example:
-
-@lisp
-(setq nnimap-split-rule 'nnimap-split-fancy
- nnimap-split-fancy ...)
-@end lisp
-
-Nnmail equivalent: @code{nnmail-split-fancy}.
-
-@item nnimap-split-download-body
-@findex nnimap-split-download-body
-@vindex nnimap-split-download-body
-
-Set to non-@code{nil} to download entire articles during splitting.
-This is generally not required, and will slow things down
-considerably. You may need it if you want to use an advanced
-splitting function that analyzes the body to split the article.

-@subsection Expiring in IMAP
-@cindex expiring @acronym{IMAP} mail
-
-Even though @code{nnimap} is not a proper @code{nnmail} derived back
-end, it supports most features in regular expiring (@pxref{Expiring
-Mail}). Unlike splitting in @acronym{IMAP} (@pxref{Splitting in
-IMAP}) it does not clone the @code{nnmail} variables (i.e., creating
-@var{nnimap-expiry-wait}) but reuse the @code{nnmail} variables. What
-follows below are the variables used by the @code{nnimap} expiry
-process.
-
-A note on how the expire mark is stored on the @acronym{IMAP} server is
-appropriate here as well. The expire mark is translated into a
-@code{imap} client specific mark, @code{gnus-expire}, and stored on the
-message. This means that likely only Gnus will understand and treat
-the @code{gnus-expire} mark properly, although other clients may allow
-you to view client specific flags on the message. It also means that
-your server must support permanent storage of client specific flags on
-messages. Most do, fortunately.
-
-If expiring @acronym{IMAP} mail seems very slow, try setting the server
-variable @code{nnimap-search-uids-not-since-is-evil}.
-
-@table @code
-
-@item nnmail-expiry-wait
-@item nnmail-expiry-wait-function
-
-These variables are fully supported. The expire value can be a
-number, the symbol @code{immediate} or @code{never}.
-
-@item nnmail-expiry-target
-
-This variable is supported, and internally implemented by calling the
-@code{nnmail} functions that handle this. It contains an optimization
-that if the destination is a @acronym{IMAP} group on the same server, the
-article is copied instead of appended (that is, uploaded again).

-@node A note on namespaces
-@subsection A note on namespaces
-@cindex IMAP namespace
-@cindex namespaces
-
-The @acronym{IMAP} protocol has a concept called namespaces, described
-by the following text in the RFC2060:
-
-@display
-5.1.2. Mailbox Namespace Naming Convention
-
- By convention, the first hierarchical element of any mailbox name
- which begins with "#" identifies the "namespace" of the remainder of
- the name. This makes it possible to disambiguate between different
- types of mailbox stores, each of which have their own namespaces.
-
- For example, implementations which offer access to USENET
- newsgroups MAY use the "#news" namespace to partition the USENET
- newsgroup namespace from that of other mailboxes. Thus, the
- comp.mail.misc newsgroup would have an mailbox name of
- "#news.comp.mail.misc", and the name "comp.mail.misc" could refer
- to a different object (e.g. a user's private mailbox).
-@end display
-
-While there is nothing in this text that warrants concern for the
-@acronym{IMAP} implementation in Gnus, some servers use namespace
-prefixes in a way that does not work with how Gnus uses mailbox names.
-
-Specifically, University of Washington's @acronym{IMAP} server uses
-mailbox names like @code{#driver.mbx/read-mail} which are valid only
-in the @sc{create} and @sc{append} commands. After the mailbox is
-created (or a messages is appended to a mailbox), it must be accessed
-without the namespace prefix, i.e. @code{read-mail}. Since Gnus do
-not make it possible for the user to guarantee that user entered
-mailbox names will only be used with the CREATE and APPEND commands,
-you should simply not use the namespace prefixed mailbox names in
-Gnus.
-
-See the UoW IMAPD documentation for the @code{#driver.*/} prefix
-for more information on how to use the prefixes. They are a power
-tool and should be used only if you are sure what the effects are.

-
-@acronym{IMAP} is a complex protocol, more so than @acronym{NNTP} or
-@acronym{POP3}. Implementation bugs are not unlikely, and we do our
-best to fix them right away. If you encounter odd behavior, chances
-are that either the server or Gnus is buggy.
-
-If you are familiar with network protocols in general, you will
-probably be able to extract some clues from the protocol dump of the

-critical to solving the problem. Therefore, we strongly encourage you
-to include the protocol dump when reporting IMAP bugs in Gnus.
-
-

-@cindex offline
-
-In the PC world people often talk about ``offline'' newsreaders. These
-are thingies that are combined reader/news transport monstrosities.
-With built-in modem programs. Yecchh!
-
-Of course, us Unix Weenie types of human beans use things like
-@code{uucp} and, like, @code{nntpd} and set up proper news and mail
-transport things like Ghod intended. And then we just use normal
-newsreaders.
-
-However, it can sometimes be convenient to do something that's a bit
-easier on the brain if you have a very slow modem, and you're not really
-that interested in doing things properly.
-
-A file format called @sc{soup} has been developed for transporting news
-and mail from servers to home machines and back again. It can be a bit
-fiddly.
-
-First some terminology:
-
-@table @dfn
-
-@item server
-This is the machine that is connected to the outside world and where you
-get news and/or mail from.
-
-@item home machine
-This is the machine that you want to do the actual reading and responding
-on. It is typically not connected to the rest of the world in any way.
-
-@item packet
-Something that contains messages and/or commands. There are two kinds
-of packets:
-
-@table @dfn
-@item message packets
-These are packets made at the server, and typically contain lots of
-messages for you to read. These are called @file{SoupoutX.tgz} by
-default, where @var{x} is a number.
-
-@item response packets
-These are packets made at the home machine, and typically contains
-replies that you've written. These are called @file{SoupinX.tgz} by
-default, where @var{x} is a number.
-
-@end table
-
-@end table
-
-
-@enumerate
-
-@item
-You log in on the server and create a @sc{soup} packet. You can either
-use a dedicated @sc{soup} thingie (like the @code{awk} program), or you
-can use Gnus to create the packet with its @sc{soup} commands (@kbd{O
-s} and/or @kbd{G s b}; and then @kbd{G s p}) (@pxref{SOUP Commands}).
-
-@item
-You transfer the packet home. Rail, boat, car or modem will do fine.
-
-@item
-You put the packet in your home directory.
-
-@item
-You fire up Gnus on your home machine using the @code{nnsoup} back end as
-the native or secondary server.
-
-@item
-You read articles and mail and answer and followup to the things you
-want (@pxref{SOUP Replies}).
-
-@item
-You do the @kbd{G s r} command to pack these replies into a @sc{soup}
-packet.
-
-@item
-You transfer this packet to the server.
-
-@item
-You use Gnus to mail this packet out with the @kbd{G s s} command.
-
-@item
-You then repeat until you die.
-
-@end enumerate

-There are many people issuing NoCeM messages. This list says what
-people you want to listen to. The default is:
-
-@lisp
-("Adri Verhoef"
- "alba-nocem@@albasani.net"
- "bleachbot@@httrack.com"
- "news@@arcor-online.net"
- "news@@uni-berlin.de"
- "nocem@@arcor.de"
- "pgpmoose@@killfile.org"
- "xjsppl@@gmx.de")
-@end lisp
-
-Known despammers that you can put in this list are listed at@*
-@uref{http://www.xs4all.nl/~rosalind/nocemreg/nocemreg.html}.
-
-You do not have to heed NoCeM messages from all these people---just the
-ones you want to listen to. You also don't have to accept all NoCeM
-messages from the people you like. Each NoCeM message has a @dfn{type}
-header that gives the message a (more or less, usually less) rigorous
-definition. Common types are @samp{spam}, @samp{spew}, @samp{mmf},
-@samp{binary}, and @samp{troll}. To specify this, you have to use
-@code{(@var{issuer} @var{conditions} @dots{})} elements in the list.
-Each condition is either a string (which is a regexp that matches types
-you want to use) or a list on the form @code{(not @var{string})}, where
-@var{string} is a regexp that matches types you don't want to use.
-
-For instance, if you want all NoCeM messages from Chris Lewis except his
-@samp{troll} messages, you'd say:
-
-@lisp
-("clewis@@ferret.ocunix.on.ca" ".*" (not "troll"))
-@end lisp
-
-On the other hand, if you just want nothing but his @samp{spam} and
-@samp{spew} messages, you'd say:
-
-@lisp
-("clewis@@ferret.ocunix.on.ca" (not ".*") "spew" "spam")
-@end lisp
-
-The specs are applied left-to-right.

-@item gnus-nocem-verifyer
-@vindex gnus-nocem-verifyer
-@findex gnus-nocem-epg-verify
-@findex pgg-verify
-This should be a function for verifying that the NoCeM issuer is who she
-says she is. This variable defaults to @code{gnus-nocem-epg-verify} if
-EasyPG is available, otherwise defaults to @code{pgg-verify}. The
-function should return non-@code{nil} if the verification is successful,
-otherwise (including the case the NoCeM message was not signed) should
-return @code{nil}. If this is too slow and you don't care for
-verification (which may be dangerous), you can set this variable to
-@code{nil}.
-
-Formerly the default was @code{mc-verify}, which is a Mailcrypt
-function. While you can still use it, you can change it into
-@code{gnus-nocem-epg-verify} or @code{pgg-verify} running with GnuPG if
-you are willing to add the @acronym{PGP} public keys to GnuPG's keyring.
-
-@item gnus-nocem-directory
-@vindex gnus-nocem-directory
-This is where Gnus will store its NoCeM cache files. The default is@*
-@file{~/News/NoCeM/}.
-
-@item gnus-nocem-expiry-wait
-@vindex gnus-nocem-expiry-wait
-The number of days before removing old NoCeM entries from the cache.
-The default is 15. If you make it shorter Gnus will be faster, but you
-might then see old spam.
-
-@item gnus-nocem-check-from
-@vindex gnus-nocem-check-from
-Non-@code{nil} means check for valid issuers in message bodies.
-Otherwise don't bother fetching articles unless their author matches a
-valid issuer; that is much faster if you are selective about the
-issuers.
-
-@item gnus-nocem-check-article-limit
-@vindex gnus-nocem-check-article-limit
-If non-@code{nil}, the maximum number of articles to check in any NoCeM
-group. @code{nil} means no restriction. NoCeM groups can be huge and
-very slow to process.
-
-@end table
-
-Using NoCeM could potentially be a memory hog. If you have many living
-(i. e., subscribed or unsubscribed groups), your Emacs process will grow
-big. If this is a problem, you should kill off all (or most) of your
-unsubscribed groups (@pxref{Subscription Commands}).

-retrieves the message headers; @code{nnimap-split-download-body} tells
-it to retrieve the message bodies as well. We don't set this by
-default because it will slow @acronym{IMAP} down, and that is not an
-appropriate decision to make on behalf of the user. @xref{Splitting
