SPF RecordsFor some reason, we have never done an article on SPF records. Here are some notes concerning SPF.
Here are our current records:
v=spf1 a mx ip4:216.245.219.162 include:_spf.freshbooks.com -all
A is for the A record
MX is for the MX record
ip4 is for a dedicated ip address.
include is for including an outside system. In this case Freshbooks which handles our billing for us.
Since A, MX and IP are all the same, only one is needed. We changed it to this:
v=spf1 mx a include:_spf.freshbooks.com -all
