[SAtalk] Deleting e-mail from a blacklisted site on a mail relay

[Allyn Baskerville]

We have a mail relay server in our firewall's DMZ, whose purpose is to send e-mails to our internal mail server and to forward the e-mails from the internal mail server to those on the Internet. This is a RH 9 running the latest qmail and spamassassin. Everything is working properly, but I would like to delete all e-mails from blacklisted sites, and just tag the other potential spam before forwarding to the internal server. I'm trying to weed through all the documentation, but any pointers would be greatly appreciated as to how this might be accomplished. TIA - Allyn
