Thank you for sharing this. I don't remember seeing errors with TLS in
the syslog. Could you share some syslog entries to check? From what I
see, for some reason you create a new tls_sessions.db file.

Have you opened a bug in Debian BTS about this?

The problem that I am observing after the update is the following at the
time of trying to deliver each mail:

----------
[/var/run/cyrus/socket/lmtp]: Permission denied
----------

The delivery is normalized after executing this command:

----------
# dpkg-statoverride --force --update --add cyrus lmtp 750
/var/run/cyrus/socket
----------

But I have noticed that after doing a reboot I have this problem again.
Any idea what could be a definitive solution?

Kind regards,
Daniel
