dovecot - Mar 2020 - 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?
