The message about the spam was in fact spam.
But, it forged a valid From: so it got through.

I'd like to fix the SPF/DKIM/spam-filter such that it more aggressively kills
this kind of forgery, assuming that wireshark.org has the right policies set.
This kind of thing is fraught with false-positives, but there are some
reasonable howtos.
