The MXes I'm responsible for don't do this (even the secondary MXes handle such cases gracefully). They just refuse messages with unknown destinations at the SMTP level. AFAIK, all MTAs which are part of Debian can do this. You need some extra configuration to cover the secondaries, too, but that's usually worth the trouble.
