If you send email from your domain you should really consider setting up a “Sender Policy Framework” (SPF) DNS record for it.
There are already great resources out there for setting up and for verifying your work; I won’t repeat them.
I WILL write about how to properly set the SPF at Network Solutions (NetSol).
After you use online resources to make up your SPF record string, at NetSol it is configured under.
Account Manager >> Dns >> Manage Advanced DNS Records >> Text (TXT Records)
Though their site has some documentation on SPF, it lacked a important piece of information.
The default TXT settings are:
* (All Others) and
Of these default fields, which one (if at all) should be overwritten?
The correct answer is, set your SPF record in the Text field of “@ (None)” line. Leave the TTL alone. Careful to add it to the right spot, adding your SPF to the “* (All Others)” won’t work, trust me I know.
That little tidbit of information may help someone.
