I am acting as the only MX for a number of domains in order to scan their email for viruses and content and then forward on via mailertable to their final destination. The problem I'm having is that spammers have begun using their domain name for sending spam...thus all of the bounces to non-existent email addresses comes back through me and then finally to postmaster@xxxxxxxxxx as undeliverable. How can I drop these non-existent addresses at my server when they are, at best, randomly generated? There are only 5 valid email addresses at this domain...I need to drop the rest. I've tried adding entries to /etc/mail/access like such: @domain.com REJECT gooduser@xxxxxxxxxx OK gooduser2@xxxxxxxxxx OK to no avail. domain.com is listed in my /etc/mail/relay-domains and NOT /etc/mail/local-host-names. Any help would be appreciated. Mike
