maybe not spyware, but i dont know what else to call it. i've been getting a few emails from servers stating that my message was undeliverable, a message i did not send to an address i don't know. is it possible there's something on my computer trying to send out emails?

This message was created automatically by mail delivery software.
A message that you sent has not yet been delivered to one or more of its
recipients after more than 72 hours on the queue on draco.webspaceserver10.com.

The message identifier is: 1GQN7M-0007el-5V
The subject of the message is: Turn your professional experience into the University Degree you deserve. CPc1sCilTi4ur

The address to which the message has not yet been delivered is:

[email protected]
(ultimately generated from [email protected])
Delay reason: SMTP error from remote mail server after end of data:
host mailin-04.mx.aol.com [64.12.138.89]: 421-:
(DYN:T1) http://postmaster.info.aol.com/errors/421dynt1.html
421 SERVICE NOT AVAILABLE

No action is required on your part. Delivery attempts will continue for
some time, and this warning may be repeated at intervals if the message
remains undelivered. Eventually the mail delivery software will give up,
and when that happens, the message will be returned to you.

It's possible, though more likely a spammer is pretending to be you. Download Little Snitch and see for yourself if anything is trying to send mail.

Someone who has you in his address book has an infected Windows computer.

Standard modus operandi for viruses is to cull all e-mail addresses from an infected computer and send itself out to all of them in the name of any of the others - i.e. any return address but the real one.

If the receiving server recognizes it as a virus and doesn't just delete it, it gets bounced - to the return address.
