Is there a way to configure logging to indicate what connection type was used to authenticate? I'd like to be able to tell from the logs whether the user used STARTTLS on port 143 or an SSL-wrapped connection on port 993. Using RC15 with auth_verbose=yes gives us the following log entries during login and logout (lines wrapped for convenience):
# login port 143 with STARTTLS: Jan 3 14:17:24 tony dovecot: [ID 107833 local5.info] imap-login: Login: user=<glenn>, method=plain, rip=10.0.0.2, lip=192.168.1.2, TLS Jan 3 14:17:41 tony dovecot: [ID 107833 local5.info] IMAP(glenn): Disconnected: Logged out
# login port 993/SSL Jan 3 14:19:11 tony dovecot: [ID 107833 local5.info] imap-login: Login: user=<glenn>, method=plain, rip=10.0.0.2, lip=192.168.1.2, TLS Jan 3 14:19:20 tony dovecot: [ID 107833 local5.info] IMAP(glenn): Disconnected: Logged out
Turning on auth_debug=yes added some additional info, but I still wasn't able to tell what port or connection type was used.
Thanks very much, Glenn
