Webmin/Vmin reverse DNS

I have a 14 IP subnet and I think mail is getting bounced because I dont have reverse lookup records setup. How do I set this up in Webmin/Vmin for all IPs?

I have read through some articles but its not making sense.

I want to do it the virtualmin/webmin way. Is there a "reverse record tool" in wmin/vmin?

Thanks,
Max
