I'm not clear what you want, do you mean that you will have
two mailservers, each will get half the number of mails ?
What will the mailservers do with the mail, route it to a third
(possibly hidden) machine ?
In that case adding a line :
IN MX 0 another.mailserver.our.domain.
would do ( using same preference, zero in this case)
If you on the other hand would like to arrange for a mailserver
that will temporarily store mail destined to your mailserver
then add a line :
IN MX 100 another.mailserver.our.domain.

Replacing bind-4 with a more modern one would make it possible
to use more reasonable timers in your SOA. The one you have
today might interfere with best practices)
