I have configured email aliases for all the members of my organization, and all the aliases use the same domain -- let's call it alias.com. Of course, each alias points to the individual person's "real" email address at home or work.
When I configure a new mail list -- firstname.lastname@example.org -- and assign addresses to it, can I fill the list with the alias addresses and expect messages and replies to function properly? I don't fully understand how email servers work, so I'm afraid that when someone sends a message to the list, the server will look up the members of the list and send the message to all those aliases, which in turn get sent to everyone's real address. So, when the recipients receive the message, I *think* their email client will display their own real address. If that person then replies to the list, the reply will fail (bounce) because that real address is not registered on the list, and the mail server won't let non-list-members send mail to the list.
Can I stuff my list with aliases and expect replies, etc to work properly?
Thank you for your time.
