I do use Claws - and have done so exclusively since it forked from sylpheed. I
also don't use *any* google 'services'. However, I've tried sending an email
via my sourceforge account and haven't (yet) seen a rejection notice, nor heard
back from the person I emailed. I'll also investigate further.

Thanks everyone for your responses.
