First of all I'm not sure where to post this. If it needs move just let me know.

I currently have an exchange 2003 email server, a Cisco ASA 5510 and a DMZ with a Barracuda spam filter. Email flows in and out of the barracuda. It's working great. We have web mail as well.

I'm getting ready to add a Proof-point email encryption device for outgoing email. I created a new dmz with a new external IP for the Proof-point server. The reason I did that is to keep it away from the web mail stuff, I’m not sure it’s needed.
1.      Is it possible to get the barracuda to send out going email to the proof-point device when the devices are in two separate dmzs?
2.      If so do I need to setup another mx dns setting so it won’t look like spam?
Am I making this way more complicated than it needs to be?
Thanks

1. you should be able to route all outbound mail to a smarthost with the IP address of your proof-point server
2. you don't need another MX record since this is only handling outbound messages. you may need to update your PTR record if mail flow begins going out of the proof-point server.
