Hello:

I'm having an issue where maradns will not do a reverse lookup for a  
particular ip address. (there may be more but I just came across this  
issue and haven't found another.)

The IP address that fails is: 68.73.75.40
Using the 4dnstools.com site I get the following answer: mailhost1.babcock.com

However, maradns correctly resolves the rDNS for "17.254.0.91" to  
"www.apple.com".

When it fails, I get, "status: SERVFAIL" and "WARNING: recursion  
requested but not available" when using dig, and "Recurs desired: 1",  
"Recurs available: 0" when using askmara.

The mararc file contains the following line:
recursive_acl = "127.0.0.1/8, 192.168.10.0/24, 192.168.23.0/24"

All of our computers using any of the above subnets fail in the same manner.

I've tested on two dns servers - one using maradns 1.3.07.08 and the  
other using maradns 1.3.13

Any help would be appreciated.
