sure. finding/correlating the information is certainly possible. i'm just cleaning up reporting atm, separating what's needed privately/locally, and what's public. the point is simply that postfix reports the reject message -- in full -- from the milter, back to the connecting sender. that's public, not private ... > If you can set what the milter returns to Postfix, you can make it obscure to > the sender but identifying for you, e.g. "Message unacceptable under Rule 34" > This is better than a completely non-identifying message, because when you > have a false positive spam rejection, the sender will be able to tell you the > specific error message, revealing to you where the issue came from. yep, that works. an additional layer of obfuscation. messy, but one makes do. not all milters allow setting the reply/reject SMTP message. for those, yet another trip to the milter logs. alternative is dump 'all' logs to logstach/splunk, and massage there.
