Outgoing mail and high availability

Dima · Joined: 05 Aug 2007 Posts: 2

Two physical and logical sites each has:

1 Edge Transport server with internet connection
1 Hub/CAS server

Incoming mail is controlled via MX record preference and works like a charm.

Is there way to automatically forward outbound mail to a Hub or an Edge in
the secondary site if the Hub/Edge in the primary site is not available?

Or do I need to add more servers to the primary site to ensure high
availability?

You can have multiple Hub Transport servers and it will use the lesser cost
route. If your primary HT server is unavailable it will use the secondary in
the other site.

I have tried shutting down the HT server in the primary site and the mail did
not flow through the second site. I did not look in to the logs assuming that
mail will not flow to the secondary site. but I will investigate it further.

Also what are my options with the Edge transport servers? Can I subscribe
both of them to both sites?
