[Dovecot] Help!

HELP!

I have installed sendmail, dovecot, and squirrel mail.  The squirrel 
mail portion of it works just fine, but I would like to have Mozilla 
Thunderbird as a client. Whenever I try and connect to the server it 
says "Thunderbird failed to find the settings for your email account."  
We do have an MX record in DNS pointing to our server. We are using 
Ubuntu 12.0.4.1, and have Dovecot 2.2.6 sendmail version 8.14.4-2ubuntu2 
We are doing this for a class project and it is due by Tuesday 10/16/2012..


Thanks,


Justin
