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.ga50...@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 postmas...@openbsd.org?
