Cybercriminals (like spammers and phishers) like to hide behind other people’s domain names via email spoofing – forging an email header to make it look like it’s coming from you and not them. When your Domain is SPF-protected, the system automatically conducts an email authentication protocol each time your domain is used for sending emails. When an unauthorised mail server or IP address uses your domain, it fails SPF authentication and will not deliver the emails.
The SPF, or Sender Policy Framework, is a system that allows you to specify mail servers and IP addresses that are authorised to send mail using your domain/s. It’s the most basic requirement that mail servers use for preliminary spam checking. But, how exactly does it work?
To protect your domain, you can manually add our SPF Record as a TXT Record.
Type | Record |
SPF/TXT | v=spf1 +a +mx include:_spf.syrahost.com ~all |
