This is true, but I would be happy to apply the policy at the entire message level. That is, it's ok to quarantine if it has *any* relay-class recipients with the wrong type OR any default-class recipients with the wrong type. I would rather quarantine the message for all recipients, even if only some are bad. Does that change your answer at all? Thanks, Philip
