* [Mail/Relay/Setup] Added a 'Mail Relay' page to the Mail menu in Setup.  Here admins can enable or disable the built-in relay authentication.  This is useful when an environment is unfriendly to the RFC-2822 spec (e.g. In-Reply-To; using Exchange and Blackberry devices) and the built-in authentication can be replaced with Virtual Attendant behavior in Mail Filtering.
* [Mail/Setup/Usability] When setting up ticket masks, the number of possible combinations is now displayed with commas as thousands separators.  For example, 123456789 is displayed as "123,456,789".  This improves readability.
[Code Cleanup/Dashboards] Fixed an issue where configuring worklist widgets on dashboards could lead to conflicts between the view_id of the widget and the worklist chooser in the popup.
