[exim] dovecot authenticator

Hello,

I am using dovecot and noticed that exim supports dovecot
authencticator. However, when I tried to use it following the handbook,
I got into all sorts of errrors.

Could anyone share a dovecot authenticator example based on a mysql
connection?

Many thanks in advance!

of course if need be I can quote the errors I get. Thank you!
