I setup auto-forwarding for a client’s Gmail account today and ran into a couple of interesting problems. Firstly, I tested the auto-forwarding function from my own Gmail account, with the forwarding email address set to my own Gmail account. After a number of attempts, i discovered that i wasn’t receiving the forwarded emails.

After playing around a bit, I discovered that the forwarded emails worked fine as long as I didn’t have the forwarding address set to the same as the address I was sending the test emails from. After sending a test email from a different account, the forwarding worked fine. Lesson: don’t try and test Gmail auto-forwarding by sending an email from the address you are forwarding back to!
