[Mailman-Users] Easy question for this crowd

Well, it was worth a try. :-/
About 12 hours after I put that RE in place, I got another one from a
different domain in '.icu'. It was held for moderation, not
8 email addresses in accept_these_nonmembers
0 email addresses in hold_these_nonmembers
0 email addresses in reject_these_nonmembers
^@.*\.icu$ in discard_these_nonmembers
'Hold' for generic_nonmember_action
'Yes' for forward_auto_discards
but it seemed to make no difference; the UCE was still held for
I'm going to try putting "from: .*@.*\.icu" in header_filter_rules and
see if that makes any difference.
Any other ideas?
