Hi again.
Well i solved _my_ problems.
These links were helpfull :
http://www.bytemark.co.uk/tech/authsmtp.html
http://article.gmane.org/gmane.mail.exim.exiscan.user/1934
The problem with the initial conf file you can find in the begining of
the thread, is that no authenticator section is defined.
I had to add it manually.
When following what is said in the first link, i had the ACL error.
the second link gave me the idea to add 'begin authenticators' at the
begining of the section .
Now it works.
Thanks to all.
