I don't think there's an easy answer to this.

My own personal choice would be to merge both incoming IPs/domains/etc. 
in the box so that it takes e-mail coming in on both IPs and uses 
whichever one I choose to be the primary one for outgoing.

I could also see myself running different sendmail processes using 
different sendmail.mc's (-> sendmail.cf's) bound to different IP 
addresses to keep them procedurally different. I could run a shared (or 
separate) MailScanner process for each, with shared .conf's and .rules 
(or separate), or using the same MySQL database.
