SPF is the acronym for Sender Policy Framework, a protection against address forgery for sending email. It identifies SMTP email servers authorized for the transport of messages through the domain name records (DNS).
Its meant, for example, to stop messages from a sender firstname.lastname@example.org from sending emails using machines not authorized by our domain for that purpose.
To configure an SPF record we need to access the domain manager that we wish to redirect. For this we access “Manage domain” from the Control Panel homepage and we take the following steps:
1.- Access the domain manager
At Domain manager, inside the section Redirections and DNS configurations we click on “Manage records”.
At the List of DNS records click on “Add” a TXT/SPF record.
Indicate the subdomain, the value and save the record.
How is it configured?
This protocol is configured by the TXT (DNS) record and as a general rule it looks like this: Subdomain: @
Value: v=spf1 mx a ptr ip4:18.104.22.168/23 include:cdmon.com include:srv.cat ~all
v defines the SPF version used (version1)
a record of the DNS for the domain
ptr authorizes the machines under the domain
IP4 v4 IP addresses
IP6 v6 IP addresses
~all Disallows machines that do not fit with that which has been explicitly authorized
Once all the data has been entered and saved, the records will be kept and can always be expanded using, http://www.openspf.org/SPF_Record_Syntax
The SPF record has been created. Now, we only need to wait until changes propagate, an action which can take anywhere between thirty minutes and an hour.
