The *_these_nonmembers checks only check one address which is what
Mailman considers the sender of the message. What address this is
depends on a config setting. The doc says:

So in your case, it may not be checking the From:

It probably should to be "^from: .*@.*\.icu\s" to avoid matching
something like

Subject: mail from: user at server.icu not discarded


From: user at sub.icure.com
