;;; Commentary:
;; Todo, major things:
;;
;; o Fix Gnus to view correct number of unread/total articles in group buffer
;; o Fix Gnus to handle leading '.' in group names (fixed?)
;; o Finish disconnected mode (moving articles between mailboxes unplugged)
;; o Sieve
;; o MIME (partial article fetches)
;; o Split to other backends, different split rules for different
;; servers/inboxes
;;
;; Todo, minor things:
;;
;; o Don't require half of Gnus -- backends should be standalone
;; o Verify that we don't use IMAP4rev1 specific things (RFC2060 App B)
;; o Dont uid fetch 1,* in nnimap-retrive-groups (slow)
;; o Split up big fetches (1,* header especially) in smaller chunks
;; o What do I do with gnus-newsgroup-*?
;; o Tell Gnus about new groups (how can we tell?)
;; o Respooling (fix Gnus?) (unnecessery?)
;; o Add support for the following: (if applicable)
;; request-list-newsgroups, request-regenerate
;; list-active-group,
;; request-associate-buffer, request-restore-buffer,
;; o Do The Right Thing when UIDVALIDITY changes (what's the right thing?)
;; o Support RFC2221 (Login referrals)
;; o IMAP2BIS compatibility? (RFC2061)
;; o ACAP stuff (perhaps a different project, would be nice to ACAPify
;; .newsrc.eld)
;; o What about Gnus's article editing, can we support it? NO!
;; o Use \Draft to support the draft group??
;; o Duplicate suppression

;; Splitting variables
(defvar nnimap-split-crosspost t
"If non-nil, do crossposting if several split methods match the mail.
If nil, the first match found will be used.")
(defvar nnimap-split-inbox nil
"*Name of mailbox to split mail from.
Mail is read from this mailbox and split according to rules in
`nnimap-split-rules'.
This can be a string or a list of strings.")
(defvar nnimap-split-rule nil
"*Mail will be split according to theese rules.
Mail is read from mailbox(es) specified in `nnimap-split-inbox'.
If you'd like, for instance, one mail group for mail from the
\"gnus-imap\" mailing list, one group for junk mail and leave
everything else in the incoming mailbox, you could do something like
this:
(setq nnimap-split-rule '((\"INBOX.gnus-imap\" \"From:.*gnus-imap\")
(\"INBOX.junk\" \"Subject:.*buy\")))
As you can see, `nnimap-split-rule' is a list of lists, where the first
element in each \"rule\" is the name of the IMAP mailbox, and the
second is a regexp that nnimap will try to match on the header to find
a fit.
The second element can also be a function. In that case, it will be
called narrowed to the headers with the first element of the rule as
the argument. It should return a non-nil value if it thinks that the
mail belongs in that group.
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 splitted to. See `nnimap-split-fancy'.
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:
(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)))))
The virtual server name is in fact a regexp, so that the same rules
may apply to several servers. In the example, the servers
\"my3server\" and \"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.")
(defvar nnimap-split-predicate "UNSEEN UNDELETED"

This will match all groups not beginning with \"INBOX\".
Note that there is nothing technically different between mail-like and
