27 ;; imap.el is a elisp library providing an interface for talking to
30 ;; imap.el is roughly divided in two parts, one that parses IMAP
31 ;; responses from the server and storing data into buffer-local
32 ;; variables, and one for utility functions which send commands to
33 ;; server, waits for an answer, and return information. The latter
34 ;; part is layered on top of the previous.
36 ;; The imap.el API consist of the following functions, other functions
37 ;; in this file should not be called directly and the result of doing
38 ;; so are at best undefined.
42 ;; imap-open, imap-opened, imap-authenticate, imap-close,
43 ;; imap-capability, imap-namespace, imap-error-text
47 ;; imap-mailbox-get, imap-mailbox-map, imap-current-mailbox,

72 ;; It is my hope that theese commands should be pretty self
73 ;; explanatory for someone that know IMAP. All functions have
74 ;; additional documentation on how to invoke them.
76 ;; imap.el support RFC1730/2060 (IMAP4/IMAP4rev1), implemented IMAP
77 ;; extensions are RFC2195 (CRAM-MD5), RFC2086 (ACL), RFC2342
78 ;; (NAMESPACE), RFC2359 (UIDPLUS), the IMAP-part of RFC2595 (STARTTLS,
79 ;; LOGINDISABLED) (with use of external library starttls.el and
80 ;; program starttls) and the GSSAPI / kerberos V4 sections of RFC1731
81 ;; (with use of external program `imtest'). It also take advantage
82 ;; the UNSELECT extension in Cyrus IMAPD.
84 ;; Without the work of John McClary Prevost and Jim Radford this library
85 ;; would not have seen the light of day. Many thanks.
87 ;; This is a transcript of short interactive session for demonstration
90 ;; (imap-open "my.mail.server")
91 ;; => " *imap* my.mail.server:0"
93 ;; The rest are invoked with current buffer as the buffer returned by
94 ;; `imap-open'. It is possible to do all without this, but it would
95 ;; look ugly here since `buffer' is always the last argument for all
96 ;; imap.el API functions.
98 ;; (imap-authenticate "myusername" "mypassword")
101 ;; (imap-mailbox-lsub "*")
102 ;; => ("INBOX.sentmail" "INBOX.private" "INBOX.draft" "INBOX.spam")
104 ;; (imap-mailbox-list "INBOX.n%")
105 ;; => ("INBOX.namedroppers" "INBOX.nnimap" "INBOX.ntbugtraq")

110 ;; (imap-mailbox-get 'exists)
113 ;; (imap-mailbox-get 'uidvalidity)
116 ;; (imap-search "FLAGGED SINCE 18-DEC-98")
119 ;; (imap-fetch 235 "RFC822.PEEK" 'RFC822)
120 ;; => "X-Sieve: cmu-sieve 1.3^M\nX-Username: <jas@pdc.kth.se>^M\r...."
124 ;; o Parse UIDs as strings? We need to overcome the 28 bit limit somehow.
125 ;; o Don't use `read' at all (important places already fixed)
126 ;; o Accept list of articles instead of message set string in most
127 ;; imap-message-* functions.
