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.
 
For example:
 
SmtpClient smtp = new SmtpClient("mail.example.com");
smtp.Credentials = null;
smtp.Send(msg);
 
 
Hope that helps,
Mike
