Hello, short of Per-Recipient Data Responses (PRDR) becoming standard,
may I ask how administrators are faking it? I understand you can
temp-fail all but the first rcpt-to, but how to do this in Postfix?
Does it require a custom milter? Surely there must be a published
solution somewhere?
I do it in a milter two ways. One, I temp-fail all but one recipient at
a time which I find problematic or two, I create a new message and
reinject it to the original recipients. I do this so I can have per
user settings on delivery and spam settings. DKIM makes this tough.
So I'm interested if you can do this in postfix as well.
