When an email is sent, the receiving server checks the SPF record of the sender's domain to determine if the sender is authorized to send emails from that domain. If the sender is not authorized, the email will be marked as spam and will not be delivered to the recipient.
It is important to setup SPF for your email deliverability because it will help to ensure that your emails are delivered to the inbox.
There are a few steps you can take to setup SPF for your email deliverability:
Register your sending domain with SPF:
In order to use SPF, you first need to register your sending domain with SPF. You can do this by adding an SPF record to your DNS settings.
Add your sending IP address to your SPF record:
Once you have registered your sending domain with SPF, you need to add your sending IP address to your SPF record. This will allow the receiving server to verify that your email is coming from a authorized IP address.
Add any other authorized IP addresses:
If you have any other authorized IP addresses that can send emails on behalf of your domain, you will need to add them to your SPF record as well.
Publish your SPF record:
Once you have added all of the necessary information to your SPF record, you need to publish it so that it can be accessed by the receiving server.
Test your SPF record:
After you have published your SPF record, you should test it to make sure it is working properly. You can do this by sending an email to a test account and checking to see if it is delivered to the inbox.
"v=spf1 ip4:192.168.0.1 a -all"
This SPF record will authorize 192.168.0.1 as a valid IP address and will mark all other IP addresses as invalid.
"v=spf1 ip4:192.168.0.1/24 a:example.com mx -all"
This SPF record will authorize all IP addresses in the 192.168.0.1/24 range as well as the example.com domain and all of its MX records.
"v=spf1 include:spf.protection.outlook.com -all"
This SPF record will include all of the IP addresses authorized by the spf.protection.outlook.com SPF record.
