26 ;;; Commentary:
28 ;; imap.el is a elisp library providing an interface for talking to
29 ;; IMAP servers.
31 ;; imap.el is roughly divided in two parts, one that parses IMAP
32 ;; responses from the server and storing data into buffer-local
33 ;; variables, and one for utility functions which send commands to
34 ;; server, waits for an answer, and return information. The latter
35 ;; part is layered on top of the previous.
37 ;; The imap.el API consist of the following functions, other functions
38 ;; in this file should not be called directly and the result of doing
39 ;; so are at best undefined.
41 ;; Global commands:
43 ;; imap-open, imap-opened, imap-authenticate, imap-close,
44 ;; imap-capability, imap-namespace, imap-error-text
46 ;; Mailbox commands:
48 ;; imap-mailbox-get, imap-mailbox-map, imap-current-mailbox,
49 ;; imap-current-mailbox-p, imap-search, imap-mailbox-select,
50 ;; imap-mailbox-examine, imap-mailbox-unselect, imap-mailbox-expunge
51 ;; imap-mailbox-close, imap-mailbox-create, imap-mailbox-delete
52 ;; imap-mailbox-rename, imap-mailbox-lsub, imap-mailbox-list
53 ;; imap-mailbox-subscribe, imap-mailbox-unsubscribe, imap-mailbox-status
54 ;; imap-mailbox-acl-get, imap-mailbox-acl-set, imap-mailbox-acl-delete
56 ;; Message commands:
58 ;; imap-fetch-asynch, imap-fetch,
59 ;; imap-current-message, imap-list-to-message-set,
60 ;; imap-message-get, imap-message-map
61 ;; imap-message-envelope-date, imap-message-envelope-subject,
62 ;; imap-message-envelope-from, imap-message-envelope-sender,
63 ;; imap-message-envelope-reply-to, imap-message-envelope-to,
64 ;; imap-message-envelope-cc, imap-message-envelope-bcc
65 ;; imap-message-envelope-in-reply-to, imap-message-envelope-message-id
66 ;; imap-message-body, imap-message-flag-permanent-p
67 ;; imap-message-flags-set, imap-message-flags-del
68 ;; imap-message-flags-add, imap-message-copyuid
69 ;; imap-message-copy, imap-message-appenduid
70 ;; imap-message-append, imap-envelope-from
71 ;; imap-body-lines
73 ;; It is my hope that these commands should be pretty self
74 ;; explanatory for someone that know IMAP. All functions have
75 ;; additional documentation on how to invoke them.
77 ;; imap.el support RFC1730/2060/RFC3501 (IMAP4/IMAP4rev1), implemented
78 ;; IMAP extensions are RFC2195 (CRAM-MD5), RFC2086 (ACL), RFC2342
79 ;; (NAMESPACE), RFC2359 (UIDPLUS), the IMAP-part of RFC2595 (STARTTLS,
80 ;; LOGINDISABLED) (with use of external library starttls.el and
81 ;; program starttls), and the GSSAPI / kerberos V4 sections of RFC1731
82 ;; (with use of external program `imtest'), RFC2971 (ID). It also
83 ;; takes advantage of the UNSELECT extension in Cyrus IMAPD.
85 ;; Without the work of John McClary Prevost and Jim Radford this library
86 ;; would not have seen the light of day. Many thanks.
88 ;; This is a transcript of short interactive session for demonstration
89 ;; purposes.
91 ;; (imap-open "my.mail.server")
92 ;; => " *imap* my.mail.server:0"
94 ;; The rest are invoked with current buffer as the buffer returned by
95 ;; `imap-open'. It is possible to do all without this, but it would
96 ;; look ugly here since `buffer' is always the last argument for all
97 ;; imap.el API functions.
99 ;; (imap-authenticate "myusername" "mypassword")
100 ;; => auth
102 ;; (imap-mailbox-lsub "*")
103 ;; => ("INBOX.sentmail" "INBOX.private" "INBOX.draft" "INBOX.spam")
105 ;; (imap-mailbox-list "INBOX.n%")
106 ;; => ("INBOX.namedroppers" "INBOX.nnimap" "INBOX.ntbugtraq")
108 ;; (imap-mailbox-select "INBOX.nnimap")
109 ;; => "INBOX.nnimap"
111 ;; (imap-mailbox-get 'exists)
112 ;; => 166
114 ;; (imap-mailbox-get 'uidvalidity)
115 ;; => "908992622"
117 ;; (imap-search "FLAGGED SINCE 18-DEC-98")
118 ;; => (235 236)
120 ;; (imap-fetch 235 "RFC822.PEEK" 'RFC822)
121 ;; => "X-Sieve: cmu-sieve 1.3^M\nX-Username: <jas@pdc.kth.se>^M\r...."
123 ;; Todo:
125 ;; o Parse UIDs as strings? We need to overcome the 28 bit limit somehow.
126 ;; o Don't use `read' at all (important places already fixed)
127 ;; o Accept list of articles instead of message set string in most
128 ;; imap-message-* functions.
129 ;; o Send strings as literal if they contain, e.g., ".
