Sorry for the delay.
That's what I thought the solution would be, but it isn't working.

I'm having an issue with Comcast's new anti-spam policy, and I'm trying to get compliant. My issue is that I send traffic out the primary ip of the Internet connection on my Sonicwall. My mail server is not sitting on the primary ip, as I have a block of addresses. So, reverse dns is failing.
I need to find out how I can setup a rule/policy/etc. that will route either:
a) all traffic out the same ip as it is natted inbound for
or
b) how to send just smtp out that ip that it is natted for
Example IP Config:
10.10.10.2 = primary wan ip
10.10.10.3 = mail server = 192.168.1.2 (server internal ip)
All traffic from mail server goes out over 10.10.10.2, and I need it to go out over 10.10.10.3 instead.
I've been playing around with Route Policies, but haven't gotten it working.
Thanks for the help!

Okay you need to go into NAT polices for this.
You need a rule specific for SMTP (so if you have it grouped with HTTP, HTTPS etc create a new one).
When you have done this then you will have a rule created that tells the firewall to send SMTP traffic outbound over X1 - usually the WAN port - in your case 10.10.10.2
You will need to create an address object called something like "SMTP OUTBOUND" and WAN HOST of 10.10.10.3
Then in the rule change it from sending out on WAN X1 to WAN SMTP OUTBOUND
Voila, your mail now goes out on the new IP.
