Hi Gerke,

Thank you for your report and glad to hear that maradns works (mostly) 
well for your use case :-)

To help find an answer to your report, can you please provide some 
further info?

1) Include a full csv1 file exhibiting the problem and not just a small 
sample like above. It is fine if you replace your domain name with 
example.com in it, just so we won't have to second guess if there are any 
other things affecting the resolving of those hostnames. The mailing list 
will probably erase attached files, so if you can provide it inline, 
that'd be great.

2) Which hostname are you looking up that exhibits this problem?

3) Which record type are you looking up that exhibits this problem? That 
is, are you asking maradns for the A record or the ANY record, or ...? If 
you don't know, the input and output of the nslookup tool used would also 
be of use.

4) Not sure if it is related, but do you have "bind_star_handling" set in 
your mararc file, and if so, to what value?

Thanks,

Remco
