Support OAuth authentication

It'd be great if envelopes supported OAuth authentication to e.g. gmail (https://developers.google.com/accounts/docs/OAuth2) with a minimum of configuration, because that's a pain to figure out. :)

Hi,
AFAIK OAuth2 is only suitable for Web apps while Envelopes operates on SMTP. As such, the issue is out of scope of this project.

Thanks for the issue and your interest in the project.

You can authenticate to gmail via oauth: sorry, I linked to the wrong page before, but https://developers.google.com/gmail/oauth_overview explains it.

Obviously, if this isn't something you're interested in implementing that's your decision. I've just recently written something that accesses my gmail account through IMAP, which should have used oauth but instead reads a plaintext password because it was too much hassle to figure out. The same thing applies to SMTP.

Hm, it looks interesting. I'm not entirely sure how would I implement that using Python's smtplib, but I'll have a look. Also, since Envelopes' job is only to send e-mails, I assume your app would get the OAuth2 token and then use it to authenticate.

Actually, this is getting far more interesting I'd expect it to be. Thanks :).
