Postscreen filtering happens when the client initially connects, even before the hostname lookup. The only postscreen whitelisting possible is by client IP. This is by design. Your choices are: - use a different IP for their MX without postscreen enabled. This can be on the same host. - turn off postscreen for everyone. -- Noel Jones
