I would want one GM account to function purely for AR. Now following things do not happen in the case of AR message:
(1). The "Reply To" does not get conveyed.
(2). The Default Footer Does Not get conveyed. I have not tested with signature though.
(3). The "From" part as seen by the recepient only has the email address instead of Name.
All the above from the same account is functional when a manually composed mail is sent. So how to achieve the same in case of AR message also....particularly point (1) as despite "please Do Not reply To This Message...notification" some users may do it and then keep receiving the same message again. They may think, wrongfully though, that something has gone wrong with our system and then cause extra time to be "wasted" by our support team explaining their errors....
