Hi guys,
I strongly believe that Option 2 (Alex/Dmitry) with Interfaces + ability to use From Email as default To Email will work the best. The main reasons are:
1. we don't want to over complicate current Users/Admin functionality/data structure
2. it's sounds more like Subscription task where ANY user can be subscribed almost to anything, this is NOT the goal here
3. we'll need to make lost of work to make this work/use all options CC/BCC/TO and other
4. not as flexible.
The only concern/question that remains here is the location of this Interface.
Option 1 - Advanced -> Email Settings sub-section
Option 2 - come up with new section under Configuration.
I am voting Option 1 for now - at least until we get to new Admin Interface questions.
I hope you are convinced.
DA
