Mailbox viruses and errors

I'm getting random e-mails attached with viruses form people on my mailing list but they did not send them. I have no virus on my computer or server. I'm using an Exchange sever to send and receive e-mail. Also when I reply an e-mail I get back an error stating that there is no mailbox for an e-mail address that doesn't match the reply address. For example, sue@hotmail.com emails me but error comes back no mailbox for sue-james@hotmail.com. Does any have any leads on what might be the problem?

Many many viruses use the technique to distribute themselves unfortunately. There's very little you can do other than to ensure that you have good, fully updating virus protection software to prevent infection and to prevent you from inadvertently acting as a distributor,
