It can be that some domains that are actually hosting their email at Google don't use Google MXes for incoming mail, but something different. I know at least a few cases when companies hosting their mail at Google use for example Proofpoint servers (*.pphosted.com) as incoming MXes for their domains. This may be the cause of the other domain not rejecting emails while gmail.com is rejecting the same emails. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub."
