[exim] Exi4 and authentication

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:
============================
smtp.tele2.it::587
============================
configuring exim4. In /etc/exim4/passwd.client I put:
============================
smtp.tele2.it:"login":"password"
============================
and created the macro file /etc/exim4/exim4.conf.localmacros
containing the following line:
============================
AUTH_CLIENT_ALLOW_NOTLS_PASSWORDS = true
============================
But in any case I'm not able to send mail
(while I receive regularly them by fetchmail/procmail.
Consider this output:
