dovecot - Jul 2019 - Dovecot v2.3.7 - TLS/SSL issue

I use a helpdesk system that connects to dovecot using POP3 with SSL enabled to
fetch the e-mails.

After I upgrade to v2.3.7 the helpdesk randomly (some times it works, some times
not) doesn't fetch the e-mails. If I configure the e-mail accounts with
SSL/TLS disabled then it works.

Any idea about this?

What was the previous version you were using? Can you send log files about the
time when it was broken? (You can send them to me privately.)
