We are using IMail 6.05 on Win 2K. The relay settings are set to 'No Mail Relay'.
Since last few months the server is trying to relay the mails to [EMAIL PROTECTED] or [EMAIL PROTECTED] While delivering such mails the SMTP process eats up 100% CPU. Even if we delete the mail from queue along with the msd file in queue it doesn't release the CPU. We have to restart the server to get back to the normal. The strange this is the sender's ID is any random ID e.g. <mailto:[EMAIL PROTECTED]>[EMAIL PROTECTED]
The only possibilities that I can think of are that a spammer guessed the password to one of your accounts, or they are sending E-mail using a deprecated routing format (such as "[EMAIL PROTECTED]"). Your SMTPD log file entries should show how they are doing this.
But last week the server accepted the mails delivery from <mailto:[EMAIL PROTECTED]>[EMAIL PROTECTED] Where 216.187.93.106 is our server's IP. But we have not setup any such server in IMail... This user was just spamming through our server.
But if 216.187.93.106 is the IP of your IMail server, how is "[EMAIL PROTECTED]" going to go to anyone outside of your server? It can't.
Why the server is acceptong such mails when the sender's IDs are invalid and the mail relay setting setup to 'No Mail Relay'..
You'll need to post the SMTPD log file entries for one of these E-mails.
