Sounds like a good idea to me. Give each user the option to
configure rules that will result in the message being rejected
already during the SMTP conversation, so that it'll not be
necessary to generate a bounce. Yes, this will probably require
implementing a new MTA which would be designed specifically to
make this approach possible, without introducing security risks.
