Today I got a bunch of e-mail Undelivered Mail Returned to Sender messages.

It appears that some spammer abuses my pe7er.com domain name as from / reply address. They forge the e-mail from / reply address in the spam, so that it looks that the e-mail was sent from pe7er.com.

The SPAM is not send from my PC, not from my mail server (smtp.pe7er.com /  ip address:  82.192.67.92), and not from my domain name.
