It won't help with Lawyers and the like who need a server stamp and the users will need to go between work and home, but there is a way to make life easy:
Make up a sub domain, something like cox.mydomain.com for each blocking ISP. On the LAN (private IP), point cox.mydomain.com at the private email server. Point the public cox.mydomain.com at the required ISPs email server. If your people run multiple ISPs or regions, you can can make extra entries, cox1.mydomain.com, cox2.mydomain.com, etc. Then configure that sub domain as the users SMTP server and they'll have context sensitive email delivery.
