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 firstname.lastname@example.org, and a few weeks later I added a new alias for that account, so that anyone can also send an email to email@example.com (as well as the original firstname.lastname@example.org).
When I reply to any email@example.com that was sent to me, can I set the send from address as firstname.lastname@example.org? Or is unchangeable and sent from the original email@example.com?
Also, is it possible to compose an original message and choose the sent from address as either firstname.lastname@example.org or email@example.com?
