Ok I have a quandry.
Emails sent to aol or comcast.net normally go through without a hitch from our exchange server. tested and works fine.
The issue arises when i have to relay an email from the webserver through the exchange server.
below is some of the code i use. it works when sending to any other domain, like gmail, but not aol and comcast.
can someone shed some light on this?
SmtpClient myClient2 = new SmtpClient("mail.server.net", 110);
myClient2.UseDefaultCredentials = false;
myClient2.Credentials = new System.Net.NetworkCredential("firstname.lastname@example.org", "password");
