Our Email server (QMail) resides off site for obvious reasons and it's running on Linux. The web server is running also on the same server and our domains points to the same machine.
My main goal is to be archiving incoming and outgoing mail! Exchange and windows have more package to accomodate that so I am thinking to be using Exchange instead.
The configuration of the Email server right now does not accommodate that and its hard to implement it the way it is set up.
I have an Exchange Mail server on our LAN and I know that I can set up the MX Record of our domains to point to the Exchange Server (incoming mails) and then can use smart host (Outgoing mail).
I have 4 questions:
1. When user want to try the web outlook remotely from their browsers how do I set it up so they can type something like ... mail.domain.com and be able to access the exchange server (web Exchange outlook) as oppose to the qmail server.
2. Also on the exchange server is there a way for a user to have the exact email alias for both of the domains. i.e email@example.com and firstname.lastname@example.org if not how do I get around it?
3. Does exchange have an intelligent antispam mechanism and antivirus or is something that I need to be looking for an add-on?
4. Security wise do you think Exchange should not be attached to the LAN and users be able to access it remotely from the internet?
