Hello.

I just took a look at your configuration file, and it appears as though 
plaintext authentication is disabled.  The default setting for 
disable_plaintext_auth is yes (search for in dovecot.conf - it's there). 
Try adding disable_plaintext_auth = no and see if this fixes your problem. 
I believe that plaintext connections to localhost are always allowed 
despite this setting.
