I have tried enabling SMTP authentication on Exim4 with very little luck. I put this in my configuration...

fixed_login:
driver = plaintext
public_name = LOGIN
server_prompts = User Name : Password
server_condition = \
${if and {{eq{$auth1}{averysecretusername}}{eq{$auth2}{anevenmoresecretpwd}}}
server_set_id = $auth1

...from the documentation at exim.org with little luck. Is there a real plain thick-as-a-brick walk through that explains how to set this up?

Everything works except the authentication and it doesn't even have to be very complicated. There is only need for one user and not even an existing one. I did find some explanations but they all deal with tweaking what already works. A pointer in the right direction would be much appreciated.

Btw, it appears to authenticate allright but it also allows non-authenticated clients.
