A customer has an Exchange 2007 server, and is having a problem with 2 customers sending them email (not all senders have this issue).

The senders get the following error.

The following recipient(s) cannot be reached:
      'FirstName LastName' on DATE TIME PM
            554 5.4.6 aliasing/forwarding loop broken (11 aliases deep; 10 max)

Not having much experience with Exchange 2007 yet, I'm a bit puzzled with this one.

That is not an Exchange error.
Is email delivered directly to the Exchange server by MX records, or does the email go in through another server?

The email is delivered to the Exchange server after being filtered by a spam filtering service.

This is the only customer I've seen this error with, and they only have a couple people who are having these problems sending to them.

So the answer to the question is no, the email is not delivered directly to the Exchange server. It goes via another server. Therefore the problem is not with Exchange. You will need to speak to the filtering service.
