Hi,

I am getting returned email that I didn't send. We don't get as many as we did but we still get them ever few days.

It is always email address's of people we don't know and sometimes it is in spanish. Some times there will be an attachment that is spam.

I run:

Microsoft Defender
Spybot
Adaware
Norton Internet Security Spyware Addition 2005
I just ran Stinger


Below is a sample:

This is the Postfix program at host mxo6.broadbandsupport.net.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to <postmaster>

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

The Postfix program

Run a virus scan.
The programs you listed seem to be for spyware & adware.

Here are 2 to choose from if you don't already have one--

Avast-

Many viruses attempt to replicate themselves by harvesting E-mail addresses on OTHER computers that they infect, then send out spam to these addresses disguised as mail-deamons. If you are certain that you did not send these out, and have run your AV and use a firewall, then you should simply delete these "error" messages. Do NOT open any attachments that may be included with the deamon.
