I just put my gmail account on my blackberry and I am encountering a countinuous problem. Whenever I send a message from my gmail account via my blackberry, the message gets sent succesfully, and it also sends me a copy of the sent message as well to my gmail account from my gmail account address.

As one could imagine this is quite annoying, I followed all correct set-up setting with POP and all, why am I having this problem?

Also, this problem only occurs when sending via blackberry, not when I send a message via computer.

Thanks in Advance!!

This question is a very common one. See this thread for fixing this issue.
