If the frequency increases, then the issue should be revisited. If we do decide this problem merits action... A simple solution would be to restrict posts to subscribers of the lists (-questions could be an exception). Another simple solution (if we are using mail filters) is to designate a group of people as spam watchers. When they spot a spam they forward it to a special addres ( i.e. spam-filter@freebsd.org), which then includes it in some sort of filter recipe. The disadvantage of such a scheme is that only subsequent spams from the poster or containing the same (body|header) are filtered. That is, the spam gets through to th list the first time. The advantage is that this whole process is only triggered when a spam is spotted. The other solutions have the disadvantage of being triggered on every post or every post by a non-subscriber. I would venture to guess that most non-subscriber posts are legitimate. Besides, most people are too busy to take on moderator roles. Although this solution obviously provides less than 100% spam free lists, I think it will prove itself pretty effective because I've noticed that most spams get sent to the list more than once-- the recent "Linus Torvalds..." spam comes to mind. Ok, my 2 cents worth has gone on too long :-) mikem. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
