Exchange isn't delivering all inbound email

I'm having trouble with inbound mail delivery.
It looks like a small amount of inbound mail isn't getting delivered to the correct mailboxes.
The only mailboxes being impacted are being polled by a service which pops them. I'm not sure if it's related.

To date, I've done the following.
I've verified with my filtering provider that the messages are being delivered to my mail server.
I set up a second box and have it set to mirror all inbound mail to the problem box (AD -> Primary account -> Forward & deliver to original boxes)
I've looked at the Event viewer. Nothing seemed out of the ordinary, but I did see some  Event 9661s I didn't recognize.
I have message tracking enabled, as well as smtp logging enabled.

Where should I go from here to determine the cause of this behavior?

Well based on the information you have provided above, trying to identify the problem is close to impossible.

Some version information would be nice.
Are you using a POP3 connector? Does that mean this is SBS?

We're running Exchange 2003, sp 2 with the  standard POP3 and SMTP virtual server.

Where does popping come in to this?

The missing messages are delivered to a few mailboxes which are popped by a program .
It looks like the fact that these messages are being popped doesn't really have anything to do with their loss. If they showed under the message center but didn't get delivered, I'd look for problems with the virtual server, but that doesn't appear to be the case.

The message tracking center doesn't contain any trace of the messages that don't get delivered, and the mailbox I set up doesn't have a copy delivered either.
I don't see any NDRs for these messages, or any entries within the event viewer.

If message tracking doesn't show the message as being delivered, then as far as I am concerned the messages were not delivered. Message tracking will show all messages that go through its transport mechanism, so even messages deleted by IMF appear in message tracking.

The only time that messages don't appear in message tracking is if you have something in front of Exchange that could be scanning the messages then passes them to Exchange, instead of being an integrated AV solution.
