"forged mail" isn't a standard postfix rejection message, so it must be in your configuration.
smtpd_recipient_restrictions = permit_mynetworks reject_unauth_destination check_sender_access hash:/etc/postfix/access_sender Thanks Craig, you've helped me solve that problem. It's in the /etc/postfix/access_sender file which is in the above main.cf line. The sole purpose of the access_sender line is to reject all mail from example.com. It turns out that server1 was routing packets tough the wrong interface and thus getting a source IP address that wasn't part of "mynetworks". -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
