;;; Commentary:
|
|
|
|
;; This library provides an elisp API for the managesieve network
|
|
;; protocol.
|
|
;;
|
|
;; It uses the SASL library for authentication, which means it
|
|
;; supports DIGEST-MD5, CRAM-MD5, SCRAM-MD5, NTLM, PLAIN and LOGIN
|
|
;; methods. STARTTLS is not well tested, but should be easy to get to
|
|
;; work if someone wants.
|
|
;;
|
|
;; The API should be fairly obvious for anyone familiar with the
|
|
;; managesieve protocol, interface functions include:
|
|
;;
|
|
;; `sieve-manage-open'
|
|
;; open connection to managesieve server, returning a buffer to be
|
|
;; used by all other API functions.
|
|
;;
|
|
;; `sieve-manage-opened'
|
|
;; check if a server is open or not
|
|
;;
|
|
;; `sieve-manage-close'
|
|
;; close a server connection.
|
|
;;
|
|
;; `sieve-manage-authenticate'
|
|
;; `sieve-manage-listscripts'
|
|
;; `sieve-manage-deletescript'
|
|
;; `sieve-manage-getscript'
|
|
;; performs managesieve protocol actions
|
|
;;
|
|
;; and that's it. Example of a managesieve session in *scratch*:
|
|
;;
|
|
;; (setq my-buf (sieve-manage-open "my.server.com"))
|
|
;; " *sieve* my.server.com:2000*"
|
|
;;
|
|
;; (sieve-manage-authenticate "myusername" "mypassword" my-buf)
|
|
;; 'auth
|
|
;;
|
|
;; (sieve-manage-listscripts my-buf)
|
|
;; ("vacation" "testscript" ("splitmail") "badscript")
