What you are describing sounds like a "MacTCP" problem (if it is a problem) as opposed to a "bridge" problem. We pass the destination "hostname" directly to the MacTCP name resolver. If you have the "domain nameserver" option checked, it is passed to this system for resolution. I don't think that MacTCP knows anything about the difference between asking for an "A" address and an "MX" address. It just wants the IP address for the specified system. Let me think about things a bit more to see if I can come up with any type of work-around. Your suggestions will be welcome, but if the only resolution is in changes to "MacTCP", you won't see these for a while since we rely on APPLE for this software. -bid- Brought to you by Super Global Mega Corp .com
