[Exim] Exim SMTP AUTH + Mysql

Hello all

I'm trying to use Exim SMTP auth for authorization on incoming SMTP relay
attempts by users. I currently am using Courier-IMAP with mysql, and it
seems possible to tie in that database to do SMTP AUTH.

Currently the passwords are stored in plaintext in the database..

I was just wondering if anyone was able to get this going and if they could
lend me a hand. I tried reading all the documentation and just got lost.

Thanks again.
