* [CHD-3157] [Mail/Usability] When using the 'Save without sending' option on mail replies, those messages are now tagged as 'saved' rather than 'sent' in the conversation history.  This feature is often used to add sensitive information to the ticket history that the recipients can only access through the Support Center using SSL.  Previously, there was no way to tell which messages were sent or only saved.
* [CHD-3764] [Mail/Compose] The compose popup now requires a 'To:' recipient if the 'Cc:' or 'Bcc:' fields are used.  Previously, if the 'To:' was blank then a ticket would be created but no mail was sent at all (regardless of Cc:/Bcc:).

* [CHD-3761] [ACL/Mail] The 'Save without sending' action on ticket replies is now a configurable permission in roles.  The action can be granted or denied to specific workers.
* [CHD-3760] [Setup/Workers/Usability] When creating or modifying a worker record, their first and last name will be set on their email address record as well (if blank).
* [Simulator] Tweaked the name generators in the simulator to create more cosmopolitan names.  Added a few new phonetics and industries to the organization name generator.

* [Virtual Attendants/Mail/Relay] Fixed an issue with the 'Relay mail to worker' action in certain Virtual Attendants behaviors.  This was showing errors in the simulator after a code change in 6.7.2.
* [CHD-3762] [Mail/Relay] The 'From:' sender on relay messages is now configurable from Setup->Mail->Relay.  In the 6.7 update, this behavior changed to always relay as the default reply-to in Cerb.  Prior to 6.7, the 'From:' address was always spoofed as the original sender (which could cause problems with mail server authentication, failing anti-spam, and not threading properly in mail readers like Gmail).  Now there is a blurb in Setup outlining the differences, and then an administrator can select either method.
