Ce n'est pas exactement ce que tu cherches mais avec mailman tu as les topics qui pourrait eventuellement faire l'affaire.
"The topic filter categorizes each incoming email message according to regular expression filters you specify below. If the message's Subject: or Keywords: header contains a match against a topic filter, the message is logically placed into a topic bucket. Each user can then choose to only receive messages from the mailing list for a particular topic bucket (or buckets). Any message not categorized in a topic bucket registered with the user is not delivered to the list.
Note that this feature only works with regular delivery, not digest delivery.
The body of the message can also be optionally scanned for Subject: and Keywords: headers, as specified by the topics_bodylines_limit configuration variable."
