Add SPF entry example.

Line 35: Line 35:

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.
