Fix SPF Compliance
Review Request #2702 — Created Nov. 11, 2011 and submitted
Currently Reviewboard sends emails with a Return-Path of the current user. This is not SPF compliant, and as a result review emails will be rejected if a user's domain implements SPF with a reject all failed messages policy and a reciever checks SPF. This corrects this by setting the From header directly instead, and passing the site default from email address as the Return-Path address. This is needed on the KDE Reviewboard instance to ensure email delivery runs well.
Local development 1.6.x instance. From header is still set correctly, whilst Return-Path is now SPF compliant.
