Exim4 and authentication

[Mauro Sacchetto <mauro.sacchetto@tele2.it>]

My new provider requests authentication to send mail,
so I found a problem with exim4 / mutt.
For the port to send mail is 587, I put the line
nel configurare exim4
smtp.tele2.it::587
configuring exim4. In in /etc/exim4/passwd.client I put:
smtp.tele2.it:*login*:*password*
and in /etc/exim4/exim4.cong.templates I put:
AUTH_CLIENT_ALLOW_NOTLS_PASSWORDS = 1
But in any case I'm not able to send mail
(while I receive regularly them by fetchmail/procmail.
Is there anything wrong or missing?
Thanx!
