Ah, I was doing fine until this point Chris - our mail server and Quick DNS
are both on the 82 box, so I've already got a record :

82.233.20.212.in-addr.groovychocolate.com. PTR ns.groovychocolate.com

Is it allowable to have both records, ie:

82.233.20.212.in-addr.groovychocolate.com. PTR mail.groovychocolate.com
82.233.20.212.in-addr.groovychocolate.com. PTR ns.groovychocolate.com

Regards, and thanks,

Stuart
