Added 2nd Exchange 2003 server, can't send external
I'm sure its something simple that I'm missing here, but I'm at a loss. I was running out of disk space on my Exchange Server, so I set up a second one, and moved about 60 mailboxes over to the new one. The move went fine, and I am able to access the mailboxes through Outlook and send emails from and to those users internally, but I can't send externally for some reason. The emails appear as sent in Outlook, but they are all sitting in the queue on the server. I did get a bunch of Delivery Status Notification (Delay) messages, but they didn't really tell me anything as to the cause. Any clues?

Do you send directly to the internet from the Exchange Servers? If so, verify that the server has access on port 25 through the firewall and has a reverse record set up for it in the external DNS.
