Can anybody explain how a domain alias deals with the reply addres.
I have my main domain: main.com
and I have an alias domain: alias.com
So mail to email@example.com is received by firstname.lastname@example.org but...
1. What does the user see when he opens his mailbox. Are all mails received by email@example.com or can he also see which mails were send to firstname.lastname@example.org
2. If he replies to a message is it automatically using email@example.com if the mail came from that domain, or will the reply adres be firstname.lastname@example.org?
