If you are running your own dns server, you could use bind's "views"
feature to have queries for mail.appl-ecosys.com that come from
internal lan hosts answered with the internal, private address for your
mail host.

You'll need to do some reading up on how to do it, but your named.conf
would go something like this:

view "internal" {
	match-clients { 192.168.1.0/24; };
	...other options...

	zone "appl-ecosys.com" {
		type master;
		file "/var/named/db.appl-ecosys.internal";
	};

view "external" {
	match-clients { any; };
	...other options...

	zone "appl-ecosys.com" {
		type master;
		file "/var/named/db.appl-ecosys.external";
	};
