SMTP - EXCHANGE Backup

12 May 2006 1:27 PM

I am getting ready for another Hurricane season in south Louisiana and would
like to use the smtp service on windows 2k3 as a backup to my exchange
server. I have purchased a new server and have it stored in a co-lo. Can
someone explain (in detail or via a KB/white paper) how to set the smtp
server at the co-lo to receive the mail and then send it to the exchange box
once it is back up and running.

* I recently tested this with my backup server (located off site from the
exchange box) and it did receive emails for the domain.

How do I get the smtp server on the windows 2003 web edition box to send the
mail it stored for the domain back to the exchange box. I have a relay set
up on the exchange box to allow relay from that IP, although I would rather
not need that.

Thanks

How to setup backup SMTP server using Windows SMTP service

In IIS Manager - Default SMTP VS - Domains - create a new domain.
- select "Remote"
- in "Domain Name" dialog box enter name of domain - let's say foo.com |
click Finish.
- Go to properties of Foo.com in list of domains - select "Allow incoming
mail to be relayed to this domain"
- You can select "Forward all mail to smart host" and enter fqdn or
external/NATted IP address of your Exchange server.
- In SMTP Virtual Server properties, select the appropriate Retry intervals,
raise the expiration timeout to appropriate/max number of days/hours you
expect your Exchange server to be unavailable.
- In public/external DNS zone, add A record for the external/NATted IP
address of that SMTP server, and create another "MX" record with a higher
preference value pointing to that A record
- Your Exchange server does not need to allow relaying from that IP - all
mail received from that SMTP server will be for the domain you setup in the
above steps (foo.com)
