Hi,
Recently we've set up a Postfix mailserver with TLS (valid Let's
Encrypt
certificate).
So I was checking the logs and I saw mail.openbsd.org connected and
disconnected but strange enough did not deliver any mail:
Sep 6 21:47:13 mx5 postfix/smtpd[938]: connect from
mail.openbsd.org[199.185.178.25]
Sep 6 21:47:14 mx5 postfix/smtpd[938]: Anonymous TLS connection
established from mail.openbsd.org[199.185.178.25]: TLSv1.2 with
cipher
ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)
Sep 6 21:47:15 mx5 postfix/smtpd[938]: disconnect from
mail.openbsd.org[199.185.178.25] ehlo=2 starttls=1 quit=1 commands=4
When I checked on the other server, it seems mail.openbsd.org
probably
tried to deliver '20200906194148.GA50189@dalek.home.local'.
The name in the MX-record matches the forward and reverse DNS, the
HELO/EHLO name and certificate.
Any idea what could have happened ?(or maybe how to contact the
person(s) running mail.openbsd.org)
With kind regards,
Leen.
Have you tried postmaster@openbsd.org?
