What does this really mean?
You get 2 servers for the price of one. Using common examples, you would receive a server in our New Jersey data
center and a VM server in our California data center. We normally set both machines up in DNS with the same hostname (mail.yourdomain.com) for MX
purposes so that incoming mail is load balanced between the 2 servers. Each server also receives a unique hostname so that you may use either server
for client access and SMTP services. Emails coming in to your email address may be delivered to either server.
Since both servers are load balanced and incoming mail is received by either server, virus and spam scanning is distributed between the two servers
effectively doubling your incoming mail capacity.
Then you may either have your users use mail.yourdomain.com to access their POP3, IMAP, and SMTP services or dedicate one machine for outgoing
mail and one for POP3 access. If you set your clients to use mail.yourdomain.com they will automatically be load balanced between the two servers.
If they receive a message on server-a but are logged into server-b, the message will automatically be replicated and appear in their mailbox on
server-b as well. If they change their password on server-b and then attempt to login to server-a, their password will automatically have been
replicated to server-a.
This effectively gives you 100% uptime since the possibility of 2 servers that are 744 miles apart (744 miles is the closest we have 2 data centers
to each other) both being offline at the same time for whatever reason is astronomical. If one server is offline, the other server will
automatically accept mail for your users and DNS will direct incoming sessions to the server that is online. No need to reconfigure client
software to use a different DNS name or change DNS entries.

Finally - redundant email for you, your business, or your clients.
