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.

Debug: SSL_get_servername() failed

[Rowan @ Jetboy]

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?

lmtp(------): Debug: SSL_get_servername() failed

I have a smoothly running dovecot 2.3.7.2 & sendmail IMAP with SSL combo on
Fedora 30.

 

However, I see oodles of these when ssl verbosity is turned up:

 

lmtp(25738): Debug: SSL_get_servername() failed

 

Should I be concerned or is there a setting that stops that?
