Do you need help creating an SPF record?
The following is additional information about the questions asked by the SPF Wizard - Tool to create SPF records.
What is your domain? Your domain name is everything to the right of the @ in your email address, for example it's the "example.com" from username@example.com.
Do your incoming MX servers also send email as your domain? The MX records for a domain are the servers listed in DNS that are responsible for receiving email sent to your domain name. If you are not sure how to answer this question it's generally going to be safe to answer yes to this question.
Does your web site send email as your domain? If you have a web site that sends email, for example a customer feedback form that creates an email, answer yes to this question.
Allow any host with a PTR that ends in your domain name to send email as your domain? DNS has mappings that go from names to IP addresses (Example Domain A 1.2.3.4), and IP addresses back to names (4.3.2.1.in-addr.arpa. PTR Example Domain The PTR records are the part of DNS commonly referred to as reverse DNS. If you're not sure how to answer this question, answer no.
List all IP addresses, in CIDR format, that are allowed to relay mail for your domain: Are there any other email addresses that are allowed to send directly to the internet using your domain name? You do not need to include IP addresses that are covered by any of the other rules, for example IP addresses that send mail through your home ISP's SMTP (outgoing) mail server. A trailing /32 can be used for an individual IP address 1.2.3.4.32. To cover an "entire network" such as 1.2.3.* use 1.2.3.0/24
List additional hostnames that are allowed to send mail as your domain: Are there any other senders you want to list by name that are allowed to send email as your domain? Type in the complete name as it appears in DNS. I prefer to list most senders by their IP addresses and network ranges and not by their name.
Include the domain of any 3rd party email services that are allowed to send mail as your domain: 3rd party email services are other senders such as email newsletter providers that are allowed to send email using your domain name. The support pages for those providers should list the name to include in your SPF record.
How strict should others treat your SPF record? I recommend starting with neutral or softfail to make sure there are no major problems with your SPF record, and then getting more strict with a fail policy (-all) after you are certain your SPF record is correct and that your contacts are not complaining about your email being rejected or delivering to their spam folders.
