Add SPF entry example.
Our domains use a non-strict (~all) [http://en.wikipedia.org/wiki/Sender_Policy_Framework SPF] records.
Our domains use a non-strict (~all) [http://en.wikipedia.org/wiki/Sender_Policy_Framework SPF] records.
You can add an spf record in the zone file in the form
hostname TXT "v=spf1 redirect=_spf.hostname.sugarlabs.org"
_spf.hostname TXT "v=spf1 ip4:IPv4_of_hostname/mask ip6:IPv6_of_hostname/64 a:hostname.sugarlabs.org mx:hostname.sugarlabs.org ~all"
The a and mx values are authorized mail server by domain name and authorized server by domain MX record, the MX record should also be defined
for hostname.
Also maintain spacing and formatting for each section you add in the zone file.
