What a nitpicking piece of software. :-)

Looks like I chose an interesting example. Here's the official data:
$ dig mail.sourceforge.net
mail.sourceforge.net. 3985 IN A 66.35.250.206
$ dig -x 66.35.250.206
206.250.35.66.in-addr.arpa. 3600 IN CNAME
206.0/24.250.35.66.in-addr.arpa.
206.0/24.250.35.66.in-addr.arpa. 683 IN PTR lists.sourceforge.net.
When I use my own configuration, I get this result instead:
$ dig -x 66.35.250.206
206.250.35.66.in-addr.arpa. 86400 IN PTR mail.sourceforge.net.
Do I understand correctly that you're suggesting to have my own server
return lists.sourceforge.net instead of mail.sourceforge.net? Is that
what you mean by "match official PTR"?
