From: yamaoka Date: Thu, 25 Mar 2004 07:32:40 +0000 (+0000) Subject: Make it fully compatible with Gnus. X-Git-Tag: t-gnus-6_17_4-quimby-~996 X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=dda4b1da39520451d25d0656bdfb2d7d1018fe67;p=elisp%2Fgnus.git- Make it fully compatible with Gnus. Don't require `advice', `pces' and `path-util'. (pop3-ssl-program-name): Use `executable-find' instead of `exec-installed-p'. (pop3-movemail): Don't use `write-region-as-binary'. (pop3-open-server): Don't use `open-network-stream-as-binary'. (pop3-open-ssl-stream): Don't use `as-binary-process'. (pop3-open-tls-stream): Ditto. (mail-source-fetch-pop): In Gnus, advise it to bind `pop3-connection-type' and `pop3-leave-mail-on-server' while fetching mails, according to `mail-sources'. --- diff --git a/lisp/pop3.el b/lisp/pop3.el index 59afc3f..6189a61 100644 --- a/lisp/pop3.el +++ b/lisp/pop3.el @@ -35,25 +35,46 @@ ;; This program was inspired by Kyle E.

You can use SSL or STARTTLS stream to connect to mail servers. +;; For example, specify the `:connection' keyword and the value pair +;; in a mail-source as follows: +;; +;;(setq mail-sources '((pop :server "pop3.mail.server" :port 995 +;; :connection ssl :authentication apop))) ;; -;;(setq mail-sources '((pop :server "POPSERVER" :port 995 :connection ssl -;; :authentication apop))) -;;(setq pop3-connection-type 'ssl) +;; For STARTTLS stream, use `tls' isntead of `ssl'. The default +;; connection type is defined by `pop3-connection-type' which +;; defaults to nil. + +;; 2. You can fetch mails without deleting them in mail servers.
