Thanks a lot,
with null credential it worked!!!
A while back I ran into troubles sending SMTP mail using postfix as
well. In my situation, I merely needed to set the Credentials property
of the SmtpClient to null before sending, then it worked fine for me.
SmtpClient smtp = new SmtpClient("mail.example.com");
smtp.Credentials = null;
Hope that helps,
