SMTP Errors

The Microsoft exchange is installed on a Windows 2000 service pack. I have a windows XP computer and sometimes when I send emails through outlook I receive this message: "There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. <*****server.*********.COM #5.5.0 smtp;554 Transaction Failed Spam Message not queued." Looks like my email automatically sends spam to a different email address and then I get this message "The following recipient(s) could not be reached: ekenin@platina.ru on 7/26/2007 3:31 PM The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the
recipient directly to find out the correct address. <mail2.platina.ru #5.1.1 SMTP; 550 <ekenin@platina.ru>,
> Recipient unknown>" That is not even my email address. Can anyone tell me what is going on and why I receive that kind of undeliverable messages, Please?

Thanks in advance!

You might have your server set to bounce spam messages back to the sending address. The problem is that the sender address is nearly always forged, so it will either bounce back to you, or get delivered to the wrong person. Another possibility is that someone else is sending spam with your address as the forged sender. The remote site is then trying to bounce the email to the sender, but this ends up with you as it is forged on the original spam.

Without the full email headers for the messages in question, it is difficult to work out exactly who is the sender, and who is the bouncer.

Joel,
Thank you very much, do you know what do I need to configure so the server does not bounce spam messages back?
