Not sure, but this _MIGHT_ be what you need (YMMV):

Subject: Quick question
I know you can bind smptd to a specific address for outgoing email. Is
it possible (or even feasible) to run multiple smtpd sessions, tying
each one to a specific IP address and routing email based on domain
name?
For instance:
{most users} ---> smtpd instance 1
{verizon.net} --> smtpd instance 2
I'm having issues sending email to verizon.net destinations and my ISP
has offered me a third (!) IP address to use. Verizon keeps insisting I
have no rDNS records and my IP is dynamically allocated. Both
statements are false.
