So, I have set up an account, for instance email@example.com. Now I would like to add an alias for that mailbox, for instance firstname.lastname@example.org.
How to do that?
In Zimbra, you have a special field “aliases”, and you just add as many aliases as you like.
So in my case, when mail is sent to email@example.com or firstname.lastname@example.org, it will came to the same mailbox.
