There is "no auth attempts", so you do not have an issue with 
authentication.

Because of the "TLS handshaking: Disconnected" it looks like the 
connection gets cut during the initial TLS handshake. To debug this, first 
increare logging, then try from localhost without encryption, e.g.:

telnet localhost 143
1 login "loginname" "password"

and watch the human friendly output. Terminate the IMAP connection via

2 logout

Maybe that client does not like your SSL cert and drops the connection 
thereof? Or maybe a firewall thinks it has to fiddle in, e.g. change 
Thunderbird to use SSL on port 993 instead of STARTTLS on 143.

Kind regards,
