[Mono-list] R: Problem with system.net.mail

[Mike Morano]

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
