Normal mail will go through rigel. It looks like I'm hosed then, host altair is just for testing. The REAL desired operation is: mail to orionsys.com -> rigel -> bbs.orionsys.com mail to bbs.orionsys.com -> rigel -> bbs.orionsys.com mail to rigel.orionsys.com -> rigel mail to altair.orionsys.com -> rigel -> altair... I just didn't want to experiment with a live system and lose everybody's email. The filtering/relay is only intended for inbound mail, each host can send directly and if contacted by name instead of using MX records, each host would accept mail. I've tried class "w" (and not), using virtusertable (and not), using mailertable (and not) and nothing delivers mail, it just bounces with various error messages to the sender or complains of the MX loop (without the class "w"). -Dave
