Net::SMTP::SSL handles this just fine.

Net::SMTP::TLS is a bit ugly. It seems unable to do any checking of
the server certificate, a limitation its inherited from the original
script it was hacked from. I suspect some people wouldn't touch this
option if that's the case (although I doubt any tin-foil hatters use
gmail anyway, and we don't use this check for SSL either).

Secondly, Net::SMTP::SSL has no problem connecting to gmail - it does
everything Net::SMTP::TLS does and more; you can use all of the
options of IO::Socket::SSL with it. A common problem seems to be not
having Authen::SASL installed (this is required to authenticate with
gmail) - the one thing Net::SMTP::TLS *does* do is auth without using
that module.

In other words, this patch should be entirely unnecessary if you have
Authen::SASL installed - could you try this? (I've checked for myself,
git-send-email sends me mail fine via gmail without this patch)

My perl knowledge is a also bit stale, havent had to use it in anger
for a few years; your code looks ok to me, its the dodgy module I'm
worried about :)
