reverse resolving

[Thomas Skyt]

Hi,

I'm having trouble setting my local Bind 8.9.3 up correctly - I need this:

a local nameserver for two domains, both under the .dk-TLD. The IP's for
the domains are in the range 192.168.1.xxx and reverse mapping is
primarily needed for sendmail and pop3 as to avoid far too large logs
containing mostly "can't resolve 192.168.1.xxx".

How do I enable some sort of reverse resolving?
