I have had reports of duplicate messages specifically from gmail/google users to our Exim mail server. I think Google decided to take exception to something that Exim returns for a successful message, and to consider delivery incomplete (and deliver again later). So far as I can tell, from debug SMTP logging on our mail server, the SMTP DATA command returns successfully from Exim and without undue delay, but Google still resends.
