Allow System Admins to change the user name of the notification email address.

We would like System Admins to be able to modify the user name part of the notification email address (not the domain). Corporate security departments prefer to write rules for allowing external emails based upon the company name rather than on a generic word such as "notifications".

Current email address: notifications@my.workfront.com

Examples if we were allowed to modify the user name:

• mycompanyname.notifications@my.workfront.com
• mycompanyname@my.workfront.com
