I've run into something strange on an HTC EVO.. In the Mail app I only have an @live.com account set up (no gmail account). Every once in a while, when I send an email using the @live.com account in the Mail app, it goes out under the @gmail.com account that was set up with the android market. Then when the recipient replies to it, it comes back to the gmail account. Since the Mail app doesn't have the gmail account set up, I never see the response unless I just happen to check it on the gmail website. Anyone have any idea what's going on and what I can do to stop this? It's caused me to miss a couple really important messages. Under accounts and sync, gmail is turned off.
