This is a strange one. This has apparently been happening for a while, but I just noticed it. When we turn on a vacation rule, either the one built into GW8 or if I create one the old fashioned way, whenever a message is replied to outside of the system the transfer fails and this message is returned to my inbox.

The attached file had the following undeliverable recipient(s):

I would expect something like this from an external application trying to use GW as a relay, but this is coming from the client. I even turned relay on just to test, and I still get this. Any ideas?
