What is in your imp/config/backends.local.php file? If you don't have  
one, there is your problem.

By default, IMP will use TLS secured IMAP connections through  
localhost (see the comments in imp/config/backends.php). If you have  
not installed a SSL certificate in your IMAP server, this will not  
work. If you have, frequently this will fail since the SSL certificate  
invariably contains a common name (CN) that does not match the hostname.

In either case you'll want to enable plaintext logins if you connect  
to your IMAP server through localhost. Which should be fine, since  
Dovecot will allow plaintext logins through localhost by default. If  
you don't have an imp/config/backends.local.php file yet, the  
following should do the trick:

   <?php
   $servers['imap']['secure'] = false;
