virus or invader?

[Huck]

I got a message saying that an email I sent was undeliverable. I didn't
send any email to this party. I have received several such messages. Is it
possible that my computer has some sort of virus that is sending messages
from my computer? If that is possible, how can I learn about it and what
can I do?

The message I got was the following:

Nope, it is much more likely that someone (read: spambot) spoofed your
address for spamming purposes and you get the return receipt from someone
that has been spammed. It is always a good practise to regularly scan your
system though with the latest anti-virus definitions.
