How to set up DNS for multiple hosts (round-robin)?

[Demani]

I have DNS set up for my domain, serving only my internal network (outside requests go to my mail/web hosting service’s DNS servers). However, they have several mail servers they use for round-robin load distribution (I assume that’s the methodology- I put the Answer result from a dig at the bottom of this post).
Is there a way to serve this adequately (perfection isn’t necessary)? Currently I have my domin turned on with Recursive searches on and Zone transfers off. I have set up one IP address under mail.domain.org and that seems to work okay- is that sufficient long term? I do realize that I need to keep an eye on my DNS to make sure nothing changes, but that was a given anyway since the machines are not under my control.
I guess the bigger question is should I even be doing this? Should I be worrying about matching DNS, or-since we are getting mail okay with only one address- should I just leave it as is?

mail.domain.org. 6823 IN A 66.33.219.40
mail.domain.org. 6823 IN A 66.33.219.41
mail.domain.org. 6823 IN A 66.33.219.37
mail.domain.org. 6823 IN A 66.33.219.38
mail.domain.org. 6823 IN A 66.33.219.39

Well then I guess I’ll just leave it- it works.

For everyone’s education the host is Dream Host. Not exactly a dream and obviously a bit on the odd side as far as implementation.
