Furthermore, they should be in your reverse zone file, not in the nextnet.com zone file. Also, there is no benefit to having 2 PTR records for the same address (207.246.235.210). Pick one, and remove the other from your reverse zone. >>QuickDNS Pro is indeed a "real" DNS server, with performance >>characteristics rivaling that of BIND.

Unfortunately, your mail server isn't running a DNS server. You need to either configure it to use your actual DNS servers instead of itself for DNS resolution, or set up BIND on MacOS X Server. Hope this helps. ____________________________________________________________________ Chris Buxton cbuxton@menandmice.com Men & Mice http://www.menandmice.com Makers of: QuickDNS Pro
