Found the problem. Well, there were several problems.
1. I was rather dense about where the mail logs were. (/var/log/mail)
2. postfix did not like the IPV6 address it got from the mail server.
It gave up in disgust whenever it saw the IP. I added
inet_protocols = ipv4
smtp_address_preference = ipv4
which cleared that problem.
3. Now it was SASL's turn:
2015-05-26T14:37:21.770844-07:00 sma-station14l postfix/error[32140]:
D0B396ECE8: to=<ji...@sohnen-moe.com>, orig_to=<FaxMaster>,
relay=none, delay=51828, delays=51828/0.18/0/0.06, dsn=4.7.0,
status=deferred (delivery temporarily suspended: SASL authentication
failed; cannot authenticate to server smtp.sma.com[192.168.69.246]:
generic failure)
"Generic failure"? Does that mean "An error occurred. Good luck with
that."?
I am quite certain that the authentication credentials
(username/password) are correct.
The fix:
smtp_sasl_auth_enable = no
4. Finally the actual source of the "pings": A FAX server was not been
properly mothballed, and was upset that the serial/TTY port to the
modem became unavailable. It sent a complaint every 5 minutes.
