Dovecot authenticates on plain text files.

You'll find attached the Dovecot config file, an example plain text 
password file, and also the complete exim4.conf file. (I run exim with a 
personalized configuration file that is made of a single exim4.conf file)

Dovecot authenticates on files that are in /etc/vmail/users/<domainname>

Exim in this config uses two file-based authenticators (plain and login) 
and a CRAM-MD5 authenticator that uses dovecot. It is a test setup, 
where the two file-based authenticators work, and the dovecot-based one 
crashes.  I have tried setting up all authenticators in Exim to run with 
the dovecot driver, and all of them crash. If I set them all up to be 
file-based, they all work.

The same exact configuration works properly on another server (same 
Debian version) and crashes on a third one.
