Because I don't want to have to bounce messages after receiving them - I want to be able to reject them during the protocol session. If I accept the message with recipients at different policy levels, then it turns out to be undeliverable to one of the recipients, I then have to figure out what to do with the message (in terms of sending back - or not sending back, depending on the type of message - a notification to the original sender, or delivering it anyway in contradiction of policy, or just dumping it on the floor, or whatever). Whereas if I can temp-fail a recipient for not being at the same policy level, I don't have this problem because I can do policy related rejects during the protocol session (using pre-data and post-data filters) when warranted. I've done a custom mod to 1.20 to handle this - it took adding one member variable to the SMTPS structure, lines to init or reset that variable in the InitSession and ResetSession routines, and about 8 lines of code in the CheckForwardPath routine. And it temp-fails with a 471, which I've verified works fine with several different mail servers I have access to. So, I'm a happy camper myself - I just thought it might be something useful to others, and wanted to open the floor to discussion. But since no one else has chimed in, I'm guessing it's probably not a "high demand" item, so probably shouldn't be added to the main distro. I can maintain my own little branch of the code base, carrying the code for this forward locally for new versions.
