The dovecot authenticator doesn't make much effort to handle the auth protocol
correctly. The protocol itself is described here:

http://wiki.dovecot.org/Authentication_Protocol

The exim dovecot auth fails to work when there are additional fields specified
by the authentication configuration (as in case of LDAP or SQL dovecot setup),
as it assumes a fixed-length array of arguments for the "OK" or "FAIL"
authentication server responses. I have written a patch which fixes the problem
and handles the protocol correctly.
