Advertising might well be setting the spam filters off.

They could have also identified you as a spammer and locked you off their mail servers.

True advertising is setting the spam filter off but I nor any one else is sending out this e-mail we just get the return e-mail from the mail server stating that Admin on 9/23/2005 8:41 AM
You do not have permission to send to this recipient. For assistance, contact your system administrator.
but no one is sending this out, do you think this is a virus taking over the mail and sending it out or ????

The Reply-to Address in the original message - if there is one - that trigger the non-delivery message can also be fake.

It can be a simple case of the email address of one or more of your users being in someone's address book on a PC that has a mail-bot virus.

Of course, the whole message can be fraudulent and its only purpose is to get the user or you to open the zipped attachment so that it can drop its payload. One form of social engineering.
