This is probably a warning that the remote side of the connection is using a self-signed certificate. You should be able to tell which connection this is from by matching 106b2cfae48c5616 to other lines in /var/log/mail. For example, in my own maillog I see things like: smtpd[8486]: 09b3582e47599342 mta connecting address=smtp://142.250.138.27:25 host=142.250.138.27 smtpd[8486]: 09b3582e47599342 mta connected smtpd[8486]: 09b3582e47599342 mta tls ciphers=TLSv1.3:TLS_CHACHA20_POLY1305_SHA256:256 smtpd[8486]: 09b3582e47599342 mta cert-check result="unverified" smtpd[8486]: 09b3582e47599342 mta delivery evpid=5e4cf104b920fff4 from=<someone@localhost> to=<someonee...@gmail.com> rcpt=<-> source="10.1.1.1" relay="142.250.138.27 (142.250.138.27)" delay=4s result="Ok" stat="250 ok 1654617630 qp 52476" smtpd[8486]: 09b3582e47599342 mta disconnected reason=quit messages=1 I've changed the addresses in the log but you get the idead (gmail has a real certificate). - todd
