I have a Postfix server that sits in front of Exchange. Exchange has anti-spam software running that will reject what it deems as spam. This is creating a problem for Postfix, which accepts a message, and tries to send it to Exchange, who then rejects it. That leaves Postfix with an email it has to try to bounce to a (usually) non-legitimate sender.
It'd be nice if Exchange accepted and then silently dropped, but that doesn't seem to be coming. So, on my part, what can I do with Postfix to drop messages that Exchange (defined through the transport file) rejects? Thanks, Chris
