Gmail app not sending/ syncing properly

[subhramani]

I have an issue with my Gmail app where I think no information is being 'sent' from the phone. I receive incoming mails, but no mails are sent. Though I delete incoming mails, the next notification which I receive when I get the next mail will show "17 mails" though I would have deleted the previous 16 emails. When I check email on my browser, all the emails what I had deleted are still there.

I have tried a factory reset and I still have a problem.
Need help

I'm having the same problem. I'm using the latest Cyanogenmod and thought it was related so I reverted. No luck. Is this a problem with google?
