Sending Email through Dual Wan Router

 We recently purchased and set up a Dual WAN router to be able to boost our internet bandwidth beyond what a single ISP can provide. Everything works fine except our outbound email is sometimes rejected, because the email will be routed through the new ISP and the IP that the recipient sees does not match the IP of our exchange server.  Is there a way to rectify this to be able to have a legitimate connection regardless of the route of the email through our router??

The way that I have been suggesting is that both connections are configured identically - so the same reverse DNS records and the A record points to both IP addresses. That will mean email comes in on both connections, but should also allow email to go out again.

we found a setting on the router (buried under Misc Option) that allows us to forward SMTP (or other protocols) to a specific WAN.
