Dear all, I add "a:relay.company.com" using the CLI in the BIND master:

company.com. 3600 IN TXT "v=spf1 mx a:relay.company.com -all"

But after restart, this change never goes to the slaves.

If I add "ip:x.x.x.x" for example, this change goes ok to the slaves.

ip: is invalid

ip4: is valid :)
ip6: is valid

and lastly a: includes ip6 on the hostnames

And from webmin interface, if I add the "a:relay.company.com" I get this error:
Failed to save record : 'relay.company.com' is not a valid host to
allow sending from

stupid webmin
