Do the messages ever get delivered? Or, are they eventually getting bounced or dropped?

Have you checked the Queues in the Exchange 2007 Exchange Management Console to determine what the retry error says?

I am guessing you might have gotten blacklisted. Check to see if your organization is listed as a spammer.
http://mxtoolbox.com/blacklists.aspx

It could also be items such as reverse IP lookup, where the IP the mail server sends from needs to resolve to your MX record.

If you double click on the queue and view the individual messages do any of the messages have error codes on them. Example 5.5.3...blah blah

Are you using a smart-host at all to send mail?

Open Exchange Management Console
Expand Organization Configuration
Select Hub Transport and select the Send Connectors tab.
Right-click on the existing Send Connector, select Properties
Go to the Network tab.

Anything configured here?
