Warning: I am old-fashioned; I believe in filtering on source, not content. Your services are special. Presumably, all of the mail for any particular list originates from the same mail server (or relatively small collection of servers). And these are "real" mail servers, not random machines with no maintainer. You can use this property to advantage here, I think. First, you can use just about any Realtime Black List (RBL)you like, since "real" mail servers have admins who keep them off of RBLs. As a minimum, I suggest using at least dsbl.org and sbl.spamhaus.org to filter mail. But you can afford to get more aggressive (the next steps up, IMO, are dynablock.easynet.nl and cbl.abuseat.org). If your volume is too high for the normal DNS queries, you can download the lists and query against a local copy. Second, you could employ a whitelist. You would have the first Email from any IP address require your manual perusal before its originating IP gets added to the whitelist. Obviously, this is much more labor-intensive :-). But it would result in essentially zero spam, save what the list itself is receiving (which is clearly Not Your Problem). - Pat _______________________________________________ Gossip mailing list [EMAIL PROTECTED] http://www.mail-archive.com/cgi-bin/mailman/listinfo/gossip
