An example @sc{imap} mail source:
@lisp
-(imap :server "mail.mycorp.com" :stream kerberos4)
+(imap :server "mail.mycorp.com" :stream kerberos4 :fetchflag "\\Seen")
@end lisp
@item webmail
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
+splitted, it is a string and the default is @samp{UNSEEN UNDELETED}.
+
+This might be useful if you use another @sc{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
