I have a procmail recipe to catch the Debian mailing list traffic : :0 * ^From debian-user-request@lists.debian.org debian I suggest you use the X-Mailing-List header instead. It's added by the mailing list manager, so it gets added to every mailing list message. -- To UNSUBSCRIBE, email to debian-user-request@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmaster@lists.debian.org
