unauthorized mail being sent from my address

[=?Utf-8?B?c2Ft?=]

I use Outlook express 6 and run Macafee virus protection. When I check my
email I have hundreds of replies telling me my sent messages were blocked by
spam blockers or the recip address is not valid. I did not sent these emails
but they show my address as the sender. I have changed my password and have
run my virus scan numerous times and it shows no virus or spyware found. Any
idea how I can stop this Thanks

This is Off Topic, but since it's a potentially serious problem, go to
http://www.pandasoftware.com/activescan and run the Panda Anti-Virus active
scan. Panda picks up stuff that no other AV product picks up.

Firstly, send messages to an appropriate group. This group is for
programming in .NET

Secondly, there is nothing you can do about this. It's a phenomenon
known as 'backscatter'. Somebody is forging your address to send spam
email, and some idiotic mail servers send out messages to the forged
address, either to say that the address doesn't exist, or that it hit a
spam filter.

(I get so many of these every day I'm tempted to meta-backscatter -
automatically send an email to po********@idiotic-domain.com to complain
about the backscatter).
