No we are talking incoming SMTP connections from legitimate email servers in order to deliver mail. For example: Sal sends email to Alex@newworlmedia.com He connects to his email server and it takes his mail. His server then tries to connect to my server to check on the validity of the address and send email. My server is buried as it is fielding incoming connections from thousands (actually only a few at a time allowed) of servers trying to send mail to newworldmedia.com (all bounce backs due to some piece of #$%^ spammer). Maybe that makes more sense. Its just this simple. Spammers can setup their software to show whatever they want as a reply to address. (the world's most insecure communication medium). God help you if their spam campaign uses your domain as a replyto: and also is sent to hundreds or thousands or millions of emails (both legitimate or malformed) because every last bounceback is coming your way and there is little to no way of stopping it short of disabling the MX for that domain. The action of mail servers bouncing back to the replyto as a matter of protocol is just plain stupid (at least in this age of spam) Nauseating. Alex (ps.... Since moving the MX to a valid IP with no mail server my system has calmed down to a point of usability (or I wouldn't see these emails from SMSI). There are still tons of errors now refusing to relay as many systems still connect to the original IP but the local DNS sees a new ip to deliver to). By tomorrow it should all but be stopped but it came at the cost of disabling a legitimate and important domain for email for 3-6 days by the time this is done. :-( Alex Alex J McCombie New World Media Chief Information Officer Box 124 888/892.6379 MartVille, NY 13111 Alex@NewWorldMedia.com http://OurClients.com Interface Designer WebDNA Programmer Database Designer ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list .
