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

95 This can be a string or a list of strings.")
97 (defvar nnimap-split-rule nil
98 "*Mail will be split according to theese rules.
100 Mail is read from mailbox(es) specified in `nnimap-split-inbox'.
102 If you'd like, for instance, one mail group for mail from the
103 \"gnus-imap\" mailing list, one group for junk mail and leave
104 everything else in the incoming mailbox, you could do something like
107 (setq nnimap-split-rule '((\"INBOX.gnus-imap\" \"From:.*gnus-imap\")
108 (\"INBOX.junk\" \"Subject:.*buy\")))
110 As you can see, `nnimap-split-rule' is a list of lists, where the first
111 element in each \"rule\" is the name of the IMAP mailbox, and the
112 second is a regexp that nnimap will try to match on the header to find
115 The second element can also be a function. In that case, it will be
116 called narrowed to the headers with the first element of the rule as
117 the argument. It should return a non-nil value if it thinks that the
118 mail belongs in that group.
120 This variable can also have a function as its value, the function will
121 be called with the headers narrowed and should return a group where it
122 thinks the article should be splitted to. See `nnimap-split-fancy'.
124 To allow for different split rules on different virtual servers, and
125 even different split rules in different inboxes on the same server,
126 the syntax of this variable have been extended along the lines of:
128 (setq nnimap-split-rule
129 '((\"my1server\" (\".*\" ((\"ding\" \"ding@gnus.org\")
130 (\"junk\" \"From:.*Simon\")))
131 (\"my2server\" (\"INBOX\" nnimap-split-fancy))
132 (\"my[34]server\" (\".*\" ((\"private\" \"To:.*Simon\")
133 (\"junk\" my-junk-func)))))
135 The virtual server name is in fact a regexp, so that the same rules
136 may apply to several servers. In the example, the servers
137 \"my3server\" and \"my4server\" both use the same rules. Similarly,
138 the inbox string is also a regexp. The actual splitting rules are as
139 before, either a function, or a list with group/regexp or
140 group/function elements.")
