Yes, of course I looked there, but I couldn't understand which one is the module I need. That's why I asked which module would you use, if all you want is read/send mail via gmail.

I'm new to this OAuth thing, and don't yet fully understand how it works. I guess I'll have to take one module, and learn how to work with it. But I don't want to spend much of time only to discover it's the wrong module.
