What I have is one single admin account in which multiple domains dump into for example firstname.lastname@example.org, email@example.com, and firstname.lastname@example.org all dump into one mailbox so that when I do a POP mail pull from email@example.com i get all the emails from all three accounts. Now I know I can separate the emails using "smart mailboxes" in mail.app for easy organization. However, when I want to send replies to the emails they are all address as being from firstname.lastname@example.org. How can I add aliases so that I can choose to have the email come from email@example.com or firstname.lastname@example.org etc ? Thanks!!
