I've setup Postfix to Dovecot LMTP delivery with mandatory TLS. Emails are being delivered with TLSv1.3 with no errors. However, setting:
verbose_ssl = yes
exposes this on each connection:
lmtp(405619): Debug: SSL_get_servername() failed
What it this mean, and what should I do about it?
It means client did not request any particular servername. That is not an error, it's a debug message. You can try configure postfix to use DNS name instead of IP, but that said, this message is harmless and can be ignored.
