Merge pull request 'mailu: ban clients that try to log in on port 25 (hq issue 708)' (#295) from fix-708-mailu-jail-port25 into main

Port 25 takes no login, so a client that tries is guessing passwords;
mailu's jail only matched Dovecot's failures and never banned them
(issue 708). Relay attempts stay unbanned: postfix already refuses them.

+// inbound mail was refused with 450 and outbound mail sat in the deferred queue for days. The parts'
+// checks judge parts; this judges the flow, from inside the postfix container, the way postfix sees it:
+//
+//   1. postfix runs (`postfix status`, standing in for the image's own check, `! /usr/libexec/postfix/master
+//      -t`, which this one replaces);
+//   2. the deferred queue (`postqueue -j`) shows no fault of this side: a recipient deferred longer than the
+//      bound because a lookup failed here, or overdue mail to three or more domains. One or two far domains
+//      that do not answer are theirs, and can stay deferred for days: said, never unhealthy, so one dead
+//      recipient does not page the operator for days;
+//   3. a public mail host's name resolves through the resolver postfix is given: a resolver that
+//      SERVFAILs refuses inbound mail before anything reaches the queue.
+//
+// The answer is the health answer every health tool gives (mesh-sdk go/health): `state`, `healthy` beside
