Anyway, I am nearly sure that at least one of the companies I used to work for had some of these "solutions" in place, given that they were using MS Exchange as mailing solution I am fairly sure it was some closed source commercial anti-spam that was doing that. I made some shell scripts back then which were sending emails on behalf of our UNIX team, and I remember we couldn't get them delivered to their Exchange server as long as we used our UX team mailbox as "From:" sender. Clearly that Exchange server was rejecting emails that were pretending to be sent out of it, while they weren't. I was looking to accomplish something similar, but seems that SA can't do that and there are probably no open source plugins or postfix hooks that allow this (so far). So yes there are definitely some solutions out there, but whether they are publicly available, I have no idea (I was actually hoping to discover some).
