I've just checked the source code of stunnel-4.26 and it does send EHLO
- unfortunately it sends "EHLO localhost"
I bet Gmail is rejecting that connection as "localhost" isn't a valid
hostname. I think it should use the current hostname instead - that
would tend to be more valid, and if not, is fixable by the host owner.
