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 firstname.lastname@example.org is received by email@example.com but...
1. What does the user see when he opens his mailbox. Are all mails received by firstname.lastname@example.org or can he also see which mails were send to email@example.com
2. If he replies to a message is it automatically using firstname.lastname@example.org if the mail came from that domain, or will the reply adres be email@example.com?
