SPF Record Generator

What is a SPF record? — The Sender Policy Framework (SPF) is an open standard specifying a technical method to prevent sender address forgery. More information is available at Open-SPF.org.

IMPORTANT: This tool currently only performs very basic validation on information entered. It is up to you to enter proper domains, IP's, etc.

ALSO, NOTE: This tool generates a zone record. For most people, you will only need the part of the record that begins with: 'v=spf1' which can be added as a 'TXT' record in your DNS.

Please enter e-mail sources, which are allowed to send e-mail on your domains' behalf. To use your DNS zone as the domain name, just enter an '@' symbol.

NOTE: You can give multiple values by separating them with a comma (,).
Policy Item Value(s) Any Description
A The IP addresses, which are pointed to by this/these A record(s).
MX The mail servers, which are present in your domains' DNS zone.
IPv4 Allow from these IPv4 addresses.
IPv6 Allow from these IPv6 addresses.
Other domains Specify domains, which SPF records you would like to add.
 
Other sources What to do when an e-mail from your domain comes from a different source.

This tool is still in beta. It is based on the project by Roy Hochstenbach. Unfortunately, it seems his website is no longer active.
