SPF, which is short for Sender Policy Framework, is an e-mail safety system, which is designed to confirm whether an email message was sent by a licensed server. Employing SPF protection for a domain name will stop the forging of email addresses generated with the domain. In layman's terms: activating this attribute for a domain generates a specific record in the Domain Name System (DNS) which contains the IP of the servers which are permitted to send emails from mail boxes under the domain. The moment this record propagates globally, it will exist on all DNS servers that route the Internet traffic. Any time an e-mail message is sent, the first DNS server it uses checks if it comes from an approved server. When it does, it's forwarded to the destination address, yet if it does not come from a server part of the SPF record for the domain, it is discarded. Thus nobody will be able to mask an e-mail address and make it look as if you're distributing spam messages. This method is also termed email spoofing.
SPF Protection in Cloud Website Hosting
You're able to enable the SPF protection service for your domain names with only a couple of clicks in the Hepsia Control Panel, which is included in our Linux cloud website hosting packages. This is performed via the section bearing the very same name and you can set up the protection for each and every domain on our exceptional cloud hosting platform. Using a really handy interface, all you will need to type in is the hostname of the mail server which will be permitted to send messages from your emails and its IPv4 or IPv6 address. Of course, you are able to include several servers as well, if needed. If your e-mails are taken care of on our end, you can also employ an even more risk-free option by placing a limit that e-mail messages can be sent only when your domain names feature our MX records. This option cannot be applied in case your site is hosted with us, while the e-mail addresses are with a third-party service provider. In either case, the SPF protection solution will vastly improve your online security and prevent other people from forging your email addresses.
