Why not configure your MTA to relay mail ONLY on encrypted authenticated sessions, and deliver locally (after some anti-spam checks) on plain sessions, all this done at port 25? I don't know about other MTAs but postfix 2.1 allows this setup. If anyone's inretested, I can post a config file that implements this. Yassen Damyanov
