Someone is spamming Hotmail or MSN using random user + your domain as a return address. You could create a nobody account to catch the bounces, then provide a spamcop report for each of the IPs he is coming from as frequently as he changes them. If he is coming from a single IP, contact Hotmail; they'd be happy to kick a mega spammer off their system.
The only way to win is make their life more miserable as long as he targets your domain. Eventually they'll learn or have such a miserable delivery rate that they'll move on to something else. ----- Original Message ----- From: "Jason Newland" <[EMAIL PROTECTED]> > 12:02 07:18 SMTPD(249C0032) [66.140.194.140] connect 207.46.181.44 port 3560 > 12:02 07:18 SMTPD(1B2D002E) [207.46.181.44] EHLO cpimssmtpoa04.msn.com > 12:02 07:18 SMTPD(1B2D002E) [207.46.181.44] MAIL FROM:<> > 12:02 07:18 SMTPD(1B2D002E) [207.46.181.44] RCPT TO:<[EMAIL PROTECTED]> > 12:02 07:18 SMTPD(1B2D002E) [207.46.181.44] ERR mail.areatech.com invalid > user <[EMAIL PROTECTED] To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
