Audit 2026-10-12, stage 2c, "Health says what is served" - the mockup
first.
TLS certificate (assumptions A-65): Postfix serves its own copy of the
mounted file, refreshed by cert-reload once a day by default, so the card
reads that copy. When the mounted file holds a renewal not taken up yet,
two facts name it (its expiry, when it was mounted) and the paragraph says
when Postfix takes it up; the help topic says the card warns once it has
waited longer than that check allows.
Wording (D-P1, D-P3): a message refused while the panel or the spam
filter does not answer is never queued, so it is not "deferred" in
Postfix's sense - the Sender check note, the sender-check and spam filter
help topics now say "refused with a temporary error". The upstream
topic's Required: mail waits in the queue while the upstream offers no
TLS or the handshake fails, and an upstream answering STARTTLS with a
permanent error bounces it (Postfix 3.7.11, src/smtp/smtp_proto.c;
smtp_trouble.c, smtp_bulk_fail()).
