|
||
;;; Commentary:
|
||
|
||
;; imap.el is a elisp library providing an interface for talking to
|
||
;; IMAP servers.
|
||
;;
|
||
;; imap.el is roughly divided in two parts, one that parses IMAP
|
||
;; responses from the server and storing data into buffer-local
|
||
;; variables, and one for utility functions which send commands to
|
||
;; server, waits for an answer, and return information. The latter
|
||
;; part is layered on top of the previous.
|
||
;;
|
||
;; The imap.el API consist of the following functions, other functions
|
||
;; in this file should not be called directly and the result of doing
|
||
;; so are at best undefined.
|
||
;;
|
||
;; Global commands:
|
||
;;
|
||
;; imap-open, imap-opened, imap-authenticate, imap-close,
|
||
;; imap-capability, imap-namespace, imap-error-text
|
||
;;
|
||
;; Mailbox commands:
|
||
;;
|
||
;; imap-mailbox-get, imap-mailbox-map, imap-current-mailbox,
|
||
;; imap-current-mailbox-p, imap-search, imap-mailbox-select,
|
||
;; imap-mailbox-examine, imap-mailbox-unselect, imap-mailbox-expunge
|
||
;; imap-mailbox-close, imap-mailbox-create, imap-mailbox-delete
|
||
;; imap-mailbox-rename, imap-mailbox-lsub, imap-mailbox-list
|
||
;; imap-mailbox-subscribe, imap-mailbox-unsubscribe, imap-mailbox-status
|
||
;; imap-mailbox-acl-get, imap-mailbox-acl-set, imap-mailbox-acl-delete
|
||
;;
|
||
;; Message commands:
|
||
;;
|
||
;; imap-fetch-asynch, imap-fetch,
|
||
;; imap-current-message, imap-list-to-message-set,
|
||
;; imap-message-get, imap-message-map
|
||
;; imap-message-envelope-date, imap-message-envelope-subject,
|

;; imap-message-envelope-from, imap-message-envelope-sender,
|

;; imap-message-envelope-cc, imap-message-envelope-bcc
|

;; imap-message-envelope-in-reply-to, imap-message-envelope-message-id
|

;; imap-message-body, imap-message-flag-permanent-p
|
||
;; imap-message-flags-set, imap-message-flags-del
|
||
;; imap-message-flags-add, imap-message-copyuid
|
||
;; imap-message-copy, imap-message-appenduid
|
||
;; imap-message-append, imap-envelope-from
|
||
;; imap-body-lines
|
||
;;
|
||
;; It is my hope that theese commands should be pretty self
|
||
;; explanatory for someone that know IMAP. All functions have
|
||
;; additional documentation on how to invoke them.
|
||
;;
|
||
;; imap.el support RFC1730/2060 (IMAP4/IMAP4rev1), implemented IMAP
|
||
;; extensions are RFC2195 (CRAM-MD5), RFC2086 (ACL), RFC2342
|
||
;; (NAMESPACE), RFC2359 (UIDPLUS), the IMAP-part of RFC2595 (STARTTLS,
|
||
;; LOGINDISABLED) (with use of external library starttls.el and
|
||
;; program starttls) and the GSSAPI / kerberos V4 sections of RFC1731
|
||
;; (with use of external program `imtest'). It also take advantage
|
||
;; the UNSELECT extension in Cyrus IMAPD.
|
||
;;
|
||
;; Without the work of John McClary Prevost and Jim Radford this library
|
||
;; would not have seen the light of day. Many thanks.

|

|

;; The rest are invoked with current buffer as the buffer returned by
|
||
;; `imap-open'. It is possible to do all without this, but it would
|
||
;; look ugly here since `buffer' is always the last argument for all
|
||
;; imap.el API functions.

|
||
;; Todo:
|
||
;;
|
||
;; o Parse UIDs as strings? We need to overcome the 28 bit limit somehow.
|
||
;; o Don't use `read' at all (important places already fixed)
|

|

;; imap-message-* functions.
