I’m trying to figure out the correct format for entering SRV records, but haven’t had much luck so far 
None of the formats I tried entering worked; they either return “bad data” (that’s what dig says) or nothing at all.
Below is the output from dig when used on one of my own domains which is hosted on bind/named - you can see that the SRV records are returned correctly in the answer section:
root@yoda:~# dig _autodiscover._tcp.fr3d.org srv
; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_5.3 <<>> _autodiscover._tcp.fr3d.org srv

This is a friend’s domain, hosted on IWorx’s djbdns, which doesn’t work:
(IWorx config: http://www.fr3d.org/ss/lando/InterWorx-CP__DNS_Records__dor.ky_-_Mozilla_Firefox_4.0_Beta_10_9189.png )
When I put the text into a hex editor, the text of the SRV records I entered looks like it’s mostly present, but the data is unusable by any apps that use SRV records.

Has anyone else had any luck getting SRV records working? Or know what format they should be entered in?
