We have set up POP3 collection for all of our Exchange users and stopped domain forwarding at the domain control panel with our ISP. We've also set up all necessary POP3 mailboxes at the domain control panel. These POP3 boxes are working very well and Exchange has no problem sending via its own SMTP.
Our issue is that while Exchange collects email from a POP3 on any other domain, it won't collect email from the original domain's POP3 boxes. Is there something I'm missing on the either the Exchange Server or SBS configuration that needs to be changed?
