Hmm as I understand, ASSP should see a message going to [email protected], not to u...@external_domain2.com like you think, because the RCPT TO: of the e-mail should be [email protected] right? Only after accepting the message, it sees your MTA generating a new e-mail coming from u...@external_domain1.com and going to u...@external_domain2.com
So you can enable localdomains and localaddresses_FLAT [email protected] is a valid address on your server, and just set 127.0.0.1 (exchange's IP) in Accept All Mail under the Relaying category. That should work. Maybe you have some other problem and you really are an open relay. You should google for open relay test and do many of those tests on your server, look in ASSP's log during it as well. If you are an open relay, please disconnect your server. In any case, after the problem is fixed it'll probably be a good idea to change your IP, you might be listed in hundreds of public and private blocklists. What's the IP? Saying this because I don't see how someone could see you as an open relay because of this, since the original RCPT TO: is to a valid e-mail in one of your domains. What is ASSP's behavior when u...@external_domain1.com tries to send directly to u...@external_domain2.com? If there are no local domains, no authenticated senders required etc. maybe it actually is an open relay. Check for it urgently!
