Hello, I am using Postfix/Dovecot/IMAP.
Everything is working fine, but I have noticed that every time I connect with Thunderbird to my server via IMAP, not one but 4 connections are being logged into /var/log/mail/mail.log: 2014-08-27 09:17:46 dovecot: imap-login: Login: user=<martin>, method=PLAIN, rip=11.22.33.44, lip=55.66.77.88, mpid=12519, TLS, session=<uyb/N5cB+gBUDFRB> 2014-08-27 09:17:53 dovecot: imap-login: Login: user=<martin>, method=PLAIN, rip=11.22.33.44, lip=55.66.77.88, mpid=12521, TLS, session=<jioqN5cB/ABUDFRB> 2014-08-27 09:17:53 dovecot: imap-login: Login: user=<martin>, method=PLAIN, rip=11.22.33.44, lip=55.66.77.88, mpid=12523, TLS, session=<pqwwN5cB/QBUDFRB> 2014-08-27 09:17:54 dovecot: imap-login: Login: user=<martin>, method=PLAIN, rip=11.22.33.44, lip=55.66.77.88, mpid=12525, TLS, session=<cffremmc/gBUDFRB> This looks like 4 separate sessions are created when I log in from one client. Is this normal behavior? Can somebody please explain why this is so? My Dovecot version is 2.1.7 regards, Martin
