* .NET 2.0 site setup on the same network/domain (different box) as the Exchange server
* Sending mail using System.Net.Mail.SmtpClient using a different remote mail server (tried the same as well)
* Mail is being delivered to all addresses EXCEPT those on the domain
(delivered to firstname.lastname@example.org but not email@example.com)
I can't find anything on people having this issue.
What do I need to do? Site is in VB but C# is fine, too.
