Exchange server on two different ISP link - 19.Jun.2007 12:57:22 AM

Hi!
I am new to Exchange setup. Our organization is setting up Exchange 2007. We have got two E1 internet links comming from two different ISPs. Both the links terminate on our Perimeter Checkpoint firewall.
After installing Exchange 2007, how do I setup the MX records on the DNS, so that the Exchange server is accessible on the internet via either of the link in case of a one link failure?
Any help / guidance will be really appreciated.
Thanks
Rishi

I believe what you need to do is enter 2 MX records in your external DNS of equal value which will point to mail1.domain.com and mail2.domain.com
then point mail1 & mail2 to the external IPs.
This is more load balencing, i am not sure if this will work if one link is down, you should test it before it goes live.
