I'm not entirely sure that I understand your problem.  If you have a unique
domain name, and your client also has a unique domain name, and your dns
records are properly configured, then sending email from domain name A to domain
name B should just work, regardless of how close your actual IP addresses are.

Having said that, you can put a domain name and IP address in /etc/hosts on the
originating computer and that computer will henceforth use the IP address
specified there.
