I keep getting msgs from unkown addresses telling me they did not accept my message because it was infected with netsky.

I have up to date antivirus software in every desktop and server, I have searched trough the registry for know keys created by netsky, and I ran netsky removal tool from Symantec in every computer. Nothing.

Still I get e-mails again and again with the same msgs.

Where else can I go to remove it?

Van,

These viruses will spoof the From address in the emails they send out. Sometimes the address it spoofs happens to be a real address, such as postmaster@yourdomain.com, or whatever. That means you conveniently get the reply or NDR from the recipient of the message.

Read here for more details:

Here is an example of the msgs I receive at least once a day.

Since I have my own may server registered let's say to "company.com", I believe the problem is here, but I've scanned with every virus removal tool my servers and my workstations, and still they don't detect anything.

I get these types of messages too, unfortunatley. Even though I'm 100% sure we're not sending out any virus infected messages. Spoofing.

So I imagine there is nothing that I can do about it unless watching my business image being hurt by this?
