More Than One Zone on a Name Server Question

[Tom Naves]

In  1.168.192.in-addr.arpa I have a PTR Record:

192.168.20.134	IN	PTR	mail.mydomain.com.

and

192.168.20.131	IN	PTR	mail2.mydomain.com.

Since mail.mydomain.net is also the alternate mail exchanger for 
mydomain.com and mail.mydomain.com is the alternate mail exchanger for 
mydomain.net how would I handle it?  Would this be good?

192.168.20.134  IN      PTR     mail.mydomain.com.
   		IN	PTR	mail2.mydomain.net.
192.168.20.131	IN	PTR	mail2.mydomain.com.
   		IN	PTR	mail.mydomain.net.

or do I need to put a second ip addr on the interface on each server?

or do I just forget about PTR records for these addresses?

Thanks,

Tom
