Looks like the issue hasn't happened again, so unfortunately I don't
have any trace.  Here are some more detailed logs from the original
issue.

Jul 13 19:49:01 mail smtpd[53491]: smtp connected address=216.126.196.35 host=1ess.inri.net
Jul 13 19:49:01 mail smtpd[53491]: smtp failed-command command="MAIL FROM:<papkarinejean@latu.my.id>" result="503 5.5.1 Invalid command: Command not allowed at this point."

Jul 13 20:58:54 mail smtpd[53491]: smtp failed-command command="Received: by mail-pj1-f45.google.com with SMTP id n11so12859079pjo.1" result="500 5.5.1 Invalid command: Command unrecognized"


The first log looks like a missing HELO/EHLO from 1ess.inri.net,
and the latter two look like email is being sent before a DATA
command. All of the remaining smtp errors in the log look like the
last two. Not sure what could be causing these..

I hope this is helpful; I'll turn on trace if the issue happens
again.
