Pass Credentials to ActionMailer's SMTP Settings from Google OAuth2

[Max Lee]

Hi,

I'm trying to send out emails by using ActionMailer's SMTP from my Gmail account logged in via Google OAuth2. 

How can I enter this user credentials such as user_name and password retrieved from Google OAuth2 into the following SMTP settings:

{

  :address => "smtp.gmail.com",

  :port => 587,

  :user_name => '<user...@gmail.com>',

  :password => '<password>',

  :authentication => "plain",

  :enable_starttls_auto => true

}

Correct if I am wrong, but the Gmail OAuth2 requires "XOAUTH2" and not "PLAIN".  The actual SMTP implementation is in Net::SMTP, but I bet you can patch that to allow for the new authentication type.
