Good idea, and clean to implement.....

If you have a lot of mailers.... You could override the hostname
pointed to by the MX record....

example.com. MX 10 mail.internal.example.com.

You could host a zone called "mail.internal.example.com" put an
A record in.

Obviously this depends on whether you need to reach the host for
other things, it isn't clean, or pretty, and should be replaced
as soon as possible with a solution like Barry's.
