the subject fields of articles. E.g. if the news group

+@vindex gnus-spam-process-newsgroups
The concepts of ham processors and spam processors are very important.
Ham processors and spam processors for a group can be set with the

will be detected later.

+thereafter. You can disable that behavior, so all unread messages
+will get the @samp{$} mark, if you set the
+@code{spam-mark-only-unseen-as-spam} parameter to nil. You should
+remove the @samp{$} mark when you are in the group summary buffer for
every message that is not spam after all. To remove the @samp{$}
mark, you can use @kbd{M-u} to ``unread'' the article, or @kbd{d} for
declaring it read the non-spam way. When you leave a group, all

+but you can customize @code{spam-split-group}.
+
+You can also give @code{spam-split} a parameter,
+e.g. @samp{'spam-use-regex-headers}. Why is this useful?
+
+Take these split rules (with @code{spam-use-regex-headers} and
+@code{spam-use-blackholes} set):
+
+@example
+ nnimap-split-fancy '(|
+ (any "ding" "ding")
+ (: spam-split)
+ ;; default mailbox
+ "mail")
+@end example
+
+Now, the problem is that you want all ding messages to make it to the
+ding folder. But that will let obvious spam (for example, spam
+detected by SpamAssassin, and @code{spam-use-regex-headers}) through,
+when it's sent to the ding list. On the other hand, some messages to
+the ding list are from a mail server in the blackhole list, so the
+invocation of @code{spam-split} can't be before the ding rule.
+
+You can let SpamAssassin headers supercede ding rules, but all other
+@code{spam-split} rules (including a second invocation of the
+regex-headers check) will be after the ding rule:
+
+@example
+ nnimap-split-fancy '(|
+ (: spam-split 'spam-use-regex-headers)
+ (any "ding" "ding")
+ (: spam-split)
+ ;; default mailbox
+ "mail")
+@end example
+
+Basically, this lets you invoke specific @code{spam-split} checks
+depending on your particular needs. You don't have to throw all mail
+into all the spam tests. Another reason why this is nice is that
+messages to mailing lists you have rules for don't have to have
+resource-intensive blackhole checks performed on them. You could also
+specify different spam checks for your nnmail split vs. your nnimap
+split. Go crazy.
+
+You still have to have specific checks such as
+@code{spam-use-regex-headers} set to t, even if you specifically
+invoke @code{spam-split} with the check. The reason is that when
+loading @code{spam.el}, some conditional loading is done depending on
+what @code{spam-use-xyz} variables you have set.
@emph{Note for IMAP users}
The boolean variable @code{nnimap-split-download-body} needs to be
set, if you want to split based on the whole message instead of just
-the headers. By default, the nnimap backend will only retrieve the
+the headers. By default, the nnimap back end will only retrieve the

+@code{nil}.
+
+@item
+Improved anti-spam features.
+
+Gnus is now able to take out spam from your mail and news streams
+using a wide variety of programs and filter rules. Among the supported
+methods are RBL blocklists, bogofilter and white/blacklists. Hooks
+for easy use of external packages such as SpamAssassin and Hashcash
+are also new. @xref{Thwarting Email Spam}.
+
+@item
+Easy inclusion of X-Faces headers.
+
+@item
+In the summary buffer, the new command @kbd{/ N} inserts new messages
+and @kbd{/ o} inserts old messages.
+
+@item
+Gnus decodes morse encoded messages if you press @kbd{W m}.
+
+@item
+Unread count correct in nnimap groups.
+
+The estimated number of unread articles in the group buffer should now
+be correct for nnimap groups. This is achieved by calling
+@code{nnimap-fixup-unread-after-getting-new-news} from the
+@code{gnus-setup-news-hook} (called on startup) and
+@code{gnus-after-getting-new-news-hook}. (called after getting new
+mail). If you have modified those variables from the default, you may
+want to add @code{nnimap-fixup-unread-after-getting-new-news} again. If
+you were happy with the estimate and want to save some (minimal) time
+when getting new mail, remove the function.
+
+@item
+Group Carbon Copy (GCC) quoting
+
+To support groups that contains SPC and other weird characters, groups
+are quoted before they are placed in the Gcc: header. This means
+variables such as @code{gnus-message-archive-group} should no longer
+contain quote characters to make groups containing SPC work. Also, if
+you are using the string @samp{nnml:foo, nnml:bar} (indicating Gcc
+into two groups) you must change it to return the list
+@code{("nnml:foo" "nnml:bar")}, otherwise the Gcc: line will be quoted
+incorrectly. Note that returning the string @samp{nnml:foo, nnml:bar}
+was incorrect earlier, it just didn't generate any problems since it
+was inserted directly.
+
+@item
+@file{~/News/overview/} not used.
+
+As a result of the following change, the @file{~/News/overview/}
+directory is not used any more. You can safely delete the entire
+hierarchy.
+
+@item
+@code{gnus-agent}
+
+The Gnus Agent has seen a major updated and is now enabled by default,
+and all nntp and nnimap servers from @code{gnus-select-method} and
+@code{gnus-secondary-select-method} are agentized by default. Earlier
+only the server in @code{gnus-select-method} was agentized by the
+default, and the agent was disabled by default. When the agent is
+enabled, headers are now also retrieved from the Agent cache instead
+of the back ends when possible. Earlier this only happened in the
+unplugged state. You can enroll or remove servers with @kbd{J a} and
+@kbd{J r} in the server buffer. Gnus will not download articles into
+the Agent cache, unless you instruct it to do so, though, by using
+@kbd{J u} or @kbd{J s} from the Group buffer. You revert to the old
+behaviour of having the Agent disabled with @code{(setq gnus-agent
+nil)}. Note that putting @code{(gnus-agentize)} in @file{~/.gnus.el}
+is not needed any more.
+
+@item
+@code{gnus-summary-line-format}
+
+The default value changed to @samp{%U%R%z%I%(%[%4L: %-23,23f%]%)
+%s\n}. Moreover @code{gnus-extra-headers},
+@code{nnmail-extra-headers} and @code{gnus-ignored-from-addresses}
+changed their default so that the users name will be replaced by the
+recipient's name or the group name posting to for @acronym{NNTP}
+groups.
+
+@item
+@file{deuglify.el} (@code{gnus-article-outlook-deuglify-article})
+
+A new file from Raymond Scholz @email{rscholz@@zonix.de} for deuglifying
+broken Outlook (Express) articles.
+
+@item
+@code{(require 'gnus-load)}
+
+If you use a stand-alone Gnus distribution, you'd better add
+@code{(require 'gnus-load)} into your @file{~/.emacs} after adding the Gnus
+lisp directory into load-path.
+
+File @file{gnus-load.el} contains autoload commands, functions and variables,
+some of which may not be included in distributions of Emacsen.
+
+@item
+@code{gnus-slave-unplugged}
+
+A new command which starts Gnus offline in slave mode.
+
+@item
+@code{message-insinuate-rmail}
+
+Adding @code{(message-insinuate-rmail)} and @code{(setq
+mail-user-agent 'gnus-user-agent)} in @file{.emacs} convinces Rmail to
+compose, reply and forward messages in message-mode, where you can
+enjoy the power of @acronym{MML}.
+
+@item
+@code{message-minibuffer-local-map}
+
+The line below enables BBDB in resending a message:
+@lisp
+(define-key message-minibuffer-local-map [(tab)]
+ 'bbdb-complete-name)
+@end lisp
+
+@item
+Externalizing and deleting of attachments.
+
+If @code{gnus-gcc-externalize-attachments} or
+@code{message-fcc-externalize-attachments} is non-@code{nil}, attach
+local files as external parts.
+
+The command @code{gnus-mime-save-part-and-strip} (bound to @kbd{C-o}
+on @acronym{MIME} buttons) saves a part and replaces the part with an
+external one. @code{gnus-mime-delete-part} (bound to @kbd{d} on
+@acronym{MIME} buttons) removes a part. It works only on back ends
+that support editing.
+
+@item
+@code{gnus-default-charset}
+
+The default value is determined from the
+@code{current-language-environment} variable, instead of
+@code{iso-8859-1}. Also the @samp{.*} item in
+@code{gnus-group-charset-alist} is removed.
+
+@item
+@code{gnus-posting-styles}
+
+Add a new format of match like
+@lisp
+((header "to" "larsi.*org")
+ (Organization "Somewhere, Inc."))
+@end lisp
+The old format like the lines below is obsolete, but still accepted.
+@lisp
+(header "to" "larsi.*org"
+ (Organization "Somewhere, Inc."))
+@end lisp
+
+@item
+@code{message-ignored-news-headers} and @code{message-ignored-mail-headers}
+
+@samp{X-Draft-From} and @samp{X-Gnus-Agent-Meta-Information} have been
+added into these two variables. If you customized those, perhaps you
+need add those two headers too.
+
+@item
+Gnus reads the @acronym{NOV} and articles in the Agent if plugged.
+
+If one reads an article while plugged, and the article already exists
+in the Agent, it won't get downloaded once more. @code{(setq
+gnus-agent-cache nil)} reverts to the old behavior.
+
+@item
+Gnus supports the ``format=flowed'' (RFC 2646) parameter. On
+composing messages, it is enabled by @code{use-hard-newlines}.
+Decoding format=flowed was present but not documented in earlier
+versions.
+
+@item
+Gnus supports the generation of RFC 2298 Disposition Notification requests.
+
+This is invoked with the @kbd{C-c M-n} key binding from message mode.
+
+@item
+Gnus supports Maildir groups.
+
+Gnus includes a new back end @file{nnmaildir.el}. @xref{Maildir}.
+
+@item
+Printing capabilities are enhanced.
+
+Gnus supports Muttprint natively with @kbd{O P} from the Summary and
+Article buffers. Also, each individual @acronym{MIME} part can be
+printed using @kbd{p} on the @acronym{MIME} button.
+
+@item
+Message supports the Importance: (RFC 2156) header.
+
+In the message buffer, @kbd{C-c C-f C-i} or @kbd{C-c C-u} cycles through
+the valid values.
+
+@item
+Gnus supports Cancel Locks in News.
+
+This means a header @samp{Cancel-Lock} is inserted in news posting. It is
+used to determine if you wrote a article or not (for cancelling and
+superseding). Gnus generates a random password string the first time
+you post a message, and saves it in your @file{~/.emacs} using the Custom
+system. While the variable is called @code{canlock-password}, it is not
+security sensitive data. Publishing your canlock string on the web
+will not allow anyone to be able to anything she could not already do.
+The behaviour can be changed by customizing @code{message-insert-canlock}.
+
+@item
+Gnus supports server-side mail filtering using Sieve.
+
+Sieve rules can be added as Group Parameters for groups, and the
+complete Sieve script is generated using @kbd{D g} from the Group
+buffer, and then uploaded to the server using @kbd{C-c C-l} in the
+generated Sieve buffer. @xref{Sieve Commands}, and the new Sieve
+manual @ref{Top, , Top, sieve, Emacs Sieve}.
+
+@item
+Extended format specs.
+
+Format spec @samp{%&user-date;} is added into
+@code{gnus-summary-line-format-alist}. Also, user defined extended
+format specs are supported. The extended format specs look like
+@samp{%u&foo;}, which invokes function
+@code{gnus-user-format-function-@var{foo}}. Because @samp{&} is used as the
+escape character, old user defined format @samp{%u&} is no longer supported.
+
+@item
+@kbd{/ *} (@code{gnus-summary-limit-include-cached}) is rewritten.
+
+It was aliased to @kbd{Y c}
+(@code{gnus-summary-insert-cached-articles}). The new function filters
+out other articles.
+
+@item
+Group names are treated as UTF-8 by default.
+
+This is supposedly what USEFOR wanted to migrate to. See
+@code{gnus-group-name-charset-group-alist} and
+@code{gnus-group-name-charset-method-alist} for customization.
+
+@item
+The nnml and nnfolder backends store marks for each groups.
+
+This makes it possible to take backup of nnml/nnfolder servers/groups
+separately of @file{~/.newsrc.eld}, while preserving marks. It also
+makes it possible to share articles and marks between users (without
+sharing the @file{~/.newsrc.eld} file) within e.g. a department. It
+works by storing the marks stored in @file{~/.newsrc.eld} in a per-group
+file @file{.marks} (for nnml) and @file{@var{groupname}.mrk} (for
+nnfolder, named @var{groupname}). If the nnml/nnfolder is moved to
+another machine, Gnus will automatically use the @file{.marks} or
+@file{.mrk} file instead of the information in @file{~/.newsrc.eld}.
+The new server variables @code{nnml-marks-is-evil} and
+@code{nnfolder-marks-is-evil} can be used to disable this feature.
+
+@item
+The menu bar item (in Group and Summary buffer) named ``Misc'' has
+been renamed to ``Gnus''.
+
+@item
+The menu bar item (in Message mode) named ``@acronym{MML}'' has been
+renamed to ``Attachments''. Note that this menu also contains security
+related stuff, like signing and encryption (@pxref{Security, Security,,
+message, Message Manual}).
+
+@item
+@code{gnus-group-charset-alist} and
+@code{gnus-group-ignored-charsets-alist}.
+
+The regexps in these variables are compared with full group names
+instead of real group names in 5.8. Users who customize these
+variables should change those regexps accordingly. For example:
+@lisp
+("^han\\>" euc-kr) -> ("\\(^\\|:\\)han\\>" euc-kr)
+@end lisp
+
+@item
+Gnus supports @acronym{PGP} (RFC 1991/2440), @acronym{PGP/MIME} (RFC
+2015/3156) and @acronym{S/MIME} (RFC 2630-2633).
+
+It needs an external @acronym{S/MIME} and OpenPGP implementation, but no
+additional Lisp libraries. This add several menu items to the
+Attachments menu, and @kbd{C-c RET} key bindings, when composing
+messages. This also obsoletes @code{gnus-article-hide-pgp-hook}.
+
+@item
+Gnus inlines external parts (message/external).
+
+@item
+@acronym{MML} (Mime compose) prefix changed from @kbd{M-m} to @kbd{C-c
+C-m}.
+
+This change was made to avoid conflict with the standard binding of
+@code{back-to-indentation}, which is also useful in message mode.

+@cindex @acronym{NOV}
When Gnus enters a group, it asks the back end for the headers of all
unread articles in the group. Most servers support the News OverView
format, which is more compact and much faster to read and parse than the
@cindex edebug
If you want to debug your problem further before reporting, possibly
in order to solve the problem yourself and send a patch, you can use
-edebug. Debugging lisp code is documented in the Elisp manual
+edebug. Debugging Lisp code is documented in the Elisp manual
(@pxref{Debugging, , Debugging Lisp Programs, elisp, The GNU Emacs
Lisp Reference Manual}). To get you started with edebug, consider if
you discover some weird behaviour when pressing @kbd{c}, the first
manifests itself by causing Gnus to be very slow. In these cases, you
can use @kbd{M-x toggle-debug-on-quit} and press @kbd{C-g} when things are
slow, and then try to analyze the backtrace (repeating the procedure
-helps isolating the real problem areas). A fancier approach is to use
-the elisp profiler, ELP. The profiler is (or should be) fully
-documented elsewhere, but to get you started there are a few steps
-that need to be followed. First, instrument the part of Gnus you are
-interested in for profiling, e.g. @kbd{M-x elp-instrument-package RET
-gnus} or @kbd{M-x elp-instrument-package RET message}. Then perform
-the operation that is slow and press @kbd{M-x elp-results}. You will
-then see which operations that takes time, and can debug them further.
-If the entire operation takes much longer than the time spent in the
-slowest function in the profiler output, you probably profiled the
-wrong part of Gnus. To reset profiling statistics, use @kbd{M-x
-elp-reset-all}. @kbd{M-x elp-restore-all} is supposed to remove
-profiling, but given the complexities and dynamic code generation in
-Gnus, it might not always work perfectly.
-
-If you just need help, you are better off asking on
-@samp{gnu.emacs.gnus}. I'm not very helpful.
