I keep getting the error "Status: 5.0.0 (Mailbox filter evaluation error)" when testing my IMS 5

This doesn't happen all the time and none of the rules in the filter file match my test.

Can you give more details, like all the changes that you have made after the default installation and the circumstances under which the error shows up.
