As far as I know, it *is* google's standard behavior.  They hide their
webmail users' real IPs, and this has resulted in a tiff with at least
one SBL because Gmail is used by many phishers for their scams and
Google wasn't very cooperative in dealing with the complaints.  So few
weeks back Google's mail was being bounced by many users of that list.

Not sure whether it has been resolved yet.
