* Updated log entry for signed certificate in Postfix. Original self signed certificate
still used in Dovecot. Note new disconnect record with information such as
<136791><t3CWAKwqpieu9RkM> before the Disconnected message. Unable to find
anything about these codes.

IMHO that has nothing to do with Postfix and/oder your certs.
Which distribution and especially which version of Dovecot are you running?
Were there changes too? On my Debian 12 with Dovecot 2.3.19 I have the same
log entries like you. And they are resulting from:
# doveconf -d | grep mail_log_prefix
mail_log_prefix = "%s(%u)<%{pid}><%{session}>: "
And in /etc/dovecot/conf.d/10-logging.conf
you can find this:
--- snip ---
##
## Log formatting.
##
[...]
# Log prefix for mail processes. See doc/wiki/Variables.txt for list of
# possible variables you can use.
#mail_log_prefix = "%s(%u)<%{pid}><%{session}>: "
--- snip ---
More details regarding the variables you can find here:
https://doc.dovecot.org/2.3/configuration_manual/config_file/config_variables/#variables-mail-service-user
And if you look at:
https://doc.dovecot.org/2.3/installation_guide/upgrading/from-2.2-to-2.3/
in the section "Changed Setting Defaults" you find this:
Setting Old Default Value New Default Value
------------------+---------------------+--------------------------
mail_log_prefix "%s(%u): " "%s(%u)<%{pid}><%{session}>: "
And that's exactly the change you observed in your log, I think.
BTW and regarding the rest of these lines: as you can also see in this
table, the default value of 'imap_logout_format' has been changed too. And
that also corresponds to your new log entries.
You could change 'imap_logout_format' and 'pop3_logout_format' (there was
no change of the default) in /etc/dovecot/conf.d/20-imap.conf resp.
/etc/dovecot/conf.d/20-pop3.conf.
So from my point of view all is looking fine. ;-)

Markus
