For an individual email account which has two or more aliases associated with a domain name, is it possible to change the sent from address to any of the aliases associated with that domain? Or am I stuck with sending from just the original alias the account was set up with?
In other words, I set up an email account with address email@example.com, and a few weeks later I added a new alias for that account, so that anyone can also send an email to firstname.lastname@example.org (as well as the original email@example.com).
When I reply to any firstname.lastname@example.org that was sent to me, can I set the send from address as email@example.com? Or is unchangeable and sent from the original firstname.lastname@example.org?
Also, is it possible to compose an original message and choose the sent from address as either email@example.com or firstname.lastname@example.org?
