Would this then be using Sendmail, Procmail, AND rblcheck? Courier MTA supports DNS black hole lists natively, without external software.

Read the documentation for spamassassin to see how per-user and global whitelist features are handled. If you want someone to intercept spam, you'd use a rule to examine the x-spam-status header after "xfilter spamc" and redirect the message to another user. That user should be globally whitelisted in your spamassassin configuration so that he/she can forward the messages to internal users. -- redhat-list mailing list unsubscribe mailto:redhat-list-request@;redhat.com?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
