Assumpte: [exim] Exim4 and client AUTH
Hi all

I have browsed the Exim archive and googled for three days, and I still
am unsuccesful in setting up AUTH on my mail server.

Basically I want my mail client to login to the exim4 mail server,
before sending the mail.

I have attached my conf file for viewing.

I have tried the MD5 and PLAIN, and nothing works.
