Hi Don, sorry you're running into forwarder trouble. From the times I've seen the '550 Headers' error message in the past, it usually has to do with the contents of particular messages forwarded to Gmail. The difficulty is, once Gmail starts to mark forwarded mail as spam or questionable, further mail sent from this address can receive more scrutiny/end up flagged as spam regardless of content. I elaborated on this a bit in an article going into the problems with using forwarders and why it is a good idea to switch over to another method of getting/checking mail. As a temporary measure, make sure you are still filtering spam out of the email that goes to your InMotion address. That way it won't be accidentally forwarded to your Gmail-- this is one of the ways that forwarding addresses often get marked as spam!
