sonicwall email secuirty

Hello Experts,

Here’s my scenario, currently we have two sonic-wall email security appliances, one virtual at our co-location and one physical at our main office. Here’s what I would like to achieve.

1.      Have both devices operational.
2.      Appliance at main office is primary and accepting all mail and delivering it to exchange. ( This is currently in place now)
3.      All necessary changes are replicated to DR virtual appliance.
4.      If main office appliance is not available for whatever reason mail is sent to virtual appliance, analyzed and then delivered to exchange.

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If you configure both email appliances the same, and have the remote one set to deliver mail to your exchange server, it should happen automatically.

All you have to do is set the two ip address in your MX records (with ISP) with different priorities.

For example:
preference = 10, mail exchanger = (primary ip address or domain name)
preference = 20, mail exhcnager = (backup ip address or domain name)

Then if the primary should fail the ISP will route the mail to the secondary.
