Mail sent to a Google Enterprise email account for a domain, sent from that domain, does not seem to get delivered.
For example, the Google account would be set up to handle email for the 'example.com' domain, and the email message in question would be sent from 'web.example.com' by a script, and would never be received. I suspect the culprit is Gmail's duplicate prevention, intended to allow mail you send to yourself to show only once in the mail display.
Has anyone dealt with this problem, and how did you work around it?
