Two bug fixes in SMTP relay service

We've just deployed two fixes to the JangoSMTP transactional email service:

1. Previously, lines in an email message that begin with a single period would result in two periods when delivered to the recipient. This was a bug related to how SMTP treats the escaping of periods. This is now fixed. To read more about issues involving SMTP and periods, see this article:

2. Previously, if an email message was relayed to and included both the Disposition-Notification-To and the Return-Receipt-To headers, then JangoSMTP would throw an error on the email message:

System.ArgumentException: An item with the same key has already been added.

This is now fixed, and email messages containing both headers will be delivered properly.
