Ok i have passed to an high log level sendmail and the problem that
give me is Login Failed i have also undestood where is the problem.
On my server some users are created so user.domain and the 
authentication for this user work fine, other users created as 
user at domain don't work because sendmail see @domain as realm but
the real user are user at domain and not just user.
Any idea to resolve?
