Email security has faced constant threats from email fraud and spam over the years. To combat these issues, experts have developed authentication techniques like SPF (Sender Policy Framework).
SPF enables domain owners to list IP addresses that are permitted to send emails on their behalf. Your domains are shielded against spam and fraud by it. and guarantees the delivery of approved emails.
The significance of SPF records and how to add an SPF record to your domain’s DNS records will be covered in this blog.
What is SPF Record & how to create it?
Add an SPF record to a domain’s DNS records.
This outlines which IP addresses are permitted to send emails on the domain’s behalf. The file is a TXT record type.
An example of an SPF Record is given below:
v=spf1 a mx ip4:220.127.116.11 include:_spf.emailclient.com ~all
You must define a list of permitted IP addresses or email servers in a certain format in order to establish an SPF record. A set of mechanisms is listed after “v=spf1,” each one separated by a space.
The record in this instance permits any server having an A or MX record. in order for the domain to send emails on its behalf. The IP addresses that are not mentioned in the SPF record are indicated by the “-all” at the conclusion of the record. The ones not on the list will then be rejected.
Why is SPF important?
The SPF protocol actively makes sure that a particular domain only sends permitted emails and forbids any unauthorized third party from doing so. Also, the SPF record of the domain included in the email’s “From” field is checked by the recipient’s email server when they receive a message. The transmitting IP address’s authorization to send emails for that domain is verified in this phase. The recipient’s email server may either classify the email as spam or reject it outright if the transmitting IP address is discovered to be unauthorized.
Domain owners may safeguard their internet reputation and prevent unauthorized use of their domain by using SPF. SPF also helps to stop email spoofing, which happens when an attacker changes the email’s origin to make it seem as though it was received from a reliable source.
How do we add an SPF Record to the Domain’s DNS Records?
After creating your SPF record, you must add it to the DNS records for your domain. Depending on your domain registrar or DNS hosting provider, the procedure for adding an SPF record to your domain’s DNS records may be different.
Here is a general guide on how to add an SPF record to your domain’s DNS records:
- Log into your account with the DNS hosting company or domain registrar.
- Find the part where you may edit the DNS records for your domain.
- Your domain needs a new TXT record, so make one.
- In the value area for the new TXT record, enter your SPF record.
- Keep the DNS records for your domain updated.
SPF records are crucial for maintaining your domain’s security against spam and forgeries. List the IP addresses that are allowed to send emails on your domain’s behalf. This will reassure the recipients of your emails that they can rely on them. It’s easy to add an SPF record to your domain’s DNS records by following the steps in this blog.
