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: 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. < #5.1.1 SMTP; 550 <>,
> 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!
