Updated Postfix with signed certificates from self signed and am experiencing several new log entries that I am unable to identify. See history that follows.
Self signed certificate in Postfix with pop3. Has worked this way since original install. Dec 29 00:12:41 mail dovecot: pop3-login: Login: user=<usr1>, method=PLAIN, rip=209.197.77.67, lip=10.0.1.211, mpid=15448, TLS, session=<CuXLvmEqzM/RxU1D> Dec 29 00:12:41 mail dovecot: pop3(usr1): Disconnected: Logged out top=0/0, retr=0/0, del=0/2825, size=204691614
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.

Issue persists and appears worse when attempting to access the mail server with the Rainloop web application. Rainloop log messages before signed certificate update appeared as the following: Dec 29 07:09:17 mail dovecot: imap-login: Login: user=<usr>, method=PLAIN, rip=10.0.1.211, lip=10.0.1.211, mpid=20215, TLS, session=<xTGtkGcqKNgKAAHT> Dec 29 07:09:17 mail dovecot: imap-login: Login: user=<usr>, method=PLAIN, rip=10.0.1.211, lip=10.0.1.211, mpid=20216, TLS, session=<azKtkGcqMtgKAAHT> Dec 29 07:09:17 mail dovecot: imap-login: Login: user=<usr>, method=PLAIN, rip=10.0.1.211, lip=10.0.1.211, mpid=20217, TLS, session=<Qz2tkGcqOtgKAAHT> Dec 29 07:09:17 mail dovecot: imap(usr): Logged out in=211 out=2047 Dec 29 07:09:17 mail dovecot: imap(usr): Logged out in=28 out=787 Dec 29 07:09:17 mail dovecot: imap(usr): Logged out in=80 out=1449 Dec 29 07:09:17 mail dovecot: imap-login: Login: user=<usr>, method=PLAIN, rip=10.0.1.211, lip=10.0.1.211, mpid=20218, TLS, session=<0EetkGcqRNgKAAHT> Dec 29 07:09:17 mail dovecot: imap(usr): Logged out in=350 out=1381 Dec 29 07:09:17 mail dovecot: imap-login: Login: user=<usr>, method=PLAIN, rip=10.0.1.211, lip=10.0.1.211, mpid=20220, TLS, session=<U8+vkGcqVNgKAAHT> Dec 29 07:09:17 mail dovecot: imap(usr): Logged out in=713 out=66680 Dec 29 07:09:24 mail dovecot: imap(usr): Connection closed (SELECT finished 0.176 secs ago) in=110 out=970
