Just a little thing I noticed..
For TXT entries like SPF, DKIM and DMARK double-quotes are required around the values for them to be valid, ex:
@ 600 IN TXT "v=spf1 a mx ~all"
And while the DNS Manager saves them just fine (verified in /var/named/chroot/var/named/domain.zone file) the entries disappear from the DNS Manager modal/lightwindow UI.
The ajax script seems to not return any of these entries with double-quotes for display in the UI.
