This guide will explain how to add an SPF record in cPanels Zone Editor, there should only be one SPF, so if an SPF record already exists then delete it and add the default record.
SPF records help email providers validate an email has been sent from a know source. This guide is to set the SPF to hard fail all emails. This record should only be added if no emails are being sent from a domain.
