Configuration is not working with Thunderbird

[Quark]

So, I have this error now:

May 22 08:54:30 ********** dovecot: imap-login: Aborted login (no auth 
attempts in 0 secs): user=<>, rip=***********, lip=***********, 
session=<***********>

I found this:  https://wiki2.dovecot.org/WhyDoesItNotWork

I have this set in my dovecot.conf: disable_plaintext_auth=yes

Same error, even when I try to connect port 143 instead of ssl (993).  
Any suggestions on what I can do now?
