;;; 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?) (unnecessary?)
|
||
;; 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
|
||
;; o Rewrite UID SEARCH UID X as UID FETCH X (UID) for those with slow servers

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 (or the
|
||
symbol `junk' if you want to remove the mail), 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."
