I am setting up a test stand alone Windows Server 2003 Standard. SMTP Server Role installed. Tried using Outlook Express on the same machine. But the e-mail stuck in the outbox. The error message:
550 5.7.1. Unable to replay for firstname.lastname@example.org
Port 25, Error Number: 0x800CCC79
I have a cable modem and a D-Link router behind the cable mode. Server has only one network card, and it gets IP from the DHCP on the router. No Exchange installed.
Thanks in advance.
