POP3 connector not passing messages to Exchange

I have SBS 2000 set up, and am using a pop3 connector to retrieve e-mail from an ISP. In the app log, I can see where it makes the connects to the isp’s pop3 server and grabs the e-mail and get a confirmation like:

Event 4024
There are 3 message(s) with a total of 46253 byte(s)

Event 4029
A message was downloaded from the POP3 server. The message ID is: MSG08042005-154529-83.MMD

Trouble is, these never seem to make it to E2k to be displayed in Outlook or OWA.
