I fear the answer to this is it's not possible but I figure if anyone would know it's the experts here. I am trying to setup someone's AOL Mail to send out emails from a different address. In other words, their email address on AOL is firstname.lastname@example.org and, like with just about any other email app, I'd like them to be able to click the dropdown by the "from" field and change it to email@example.com. The "someotherdomain" address is a functioning redirect to their AOL address so if there was some way to authorize it (like with Gmail or Yahoo), it could be authorized.
But unlike Yahoo or Gmail, can't figure out where this can be setup. Like I said, I fear it can't. But thought I would check.
Thanks in advance for any help.
