You must add Network Solutions in your SPF record to enable SPF for Network Solutions. This will allow you to add Network Solutions to your list of SPF-verified transmitting sources. As a result, the next time your company sends an email utilising Network Solutions as a third-party vendor, the email will pass SPF and the recipient's inbox will display your domain name.
Open your DNS management console
Go to the domain for which you want to setup SPF for Network Solutions
Now, If you have a pre-existing SPF record in your DNS:
You need to add spf.netsolmail.net (for non-hosted email) or spf.registeredsite.com (for hosted email) to your previous SPF record. Hence, if your previous SPF record prior to this was v=spf1 include:_spf.google.com -all, your new record will be:
v=spf1 include:_spf.google.com include:spf.netsolmail.net -all
Note: You need to ensure that you have only 1 SPF record configured for your domain. More than one record will break SPF and lead to SPF failure for legitimate emails.
In case you don’t have a pre-existing SPF record in your DNS:
Simply add the following DNS TXT SPF record to your DNS:
v=spf1 include:spf.netsolmail.net -all
