:any ideas?


@                       IN  TXT         "v=spf1 +mx ~all"

This works perfectly for me, and has for many years.

Obvious questions:
 - did you bump your SOA?
 - do your dns slaves have it?
   (ns1 and ns3 seem to have it, but not ns2)
 - which server are you testing against?
 - negative caching?

It does seem to work for me:
$  dig +short TXT @ns1.itadmins.net itadmins.net
"v=spf1 mx -all"
