Hopefully I am NOT the one everyone seems to be waiting on to supply "the outcome of the intervening discussion"? If you are, then please be advised: Not going to happen.
Because I was NOT advocating either for or against ANY particular "outcome". Simply reporting the facts as I see them, and nothing but the facts, so that:
• Someone wouldn't get the clever idea that they could bypass the /dev/null assigned by the parser by plugging the unmunged reporting addr into the "user notice" field.
• Some other one(s) wouldn't be surprised (as I was) when, after spending far too much time finding a suitable reporting addr, SpamCop promptly routed my "user notice" to /dev/null.
IOW, I'm OK with the current outcomes. Just wish they had been documented somewhere. Would have saved me some consternation I didn't need.
