SPF, which abbreviates Sender Policy Framework, is a verification system that is aimed at blocking the so-called e-mail forging. Basically, it indicates sending some message from one email address and making it seem to be sent from another one with the purpose to scam in some way the individual receiving it. When the SPF protection is active for a domain, a record that contains all mail servers authorized to send messages with addresses part of the domain is made. The record is kept on all the DNS servers that direct the Internet traffic worldwide, so that they all will identify whether an e-mail message comes from a legitimate server or not. The check is conducted at the first server where the e-mail goes through and in the first case the message is forwarded, while in the second one it is removed and it never reaches the intended recipient. Applying SPF records for your domain names will stop any unauthorized people from making use of your email addresses for harmful purposes.
SPF Protection in Cloud Web Hosting
When you host your domains in a cloud web hosting account with us and we handle the emails for them, you'll be able to activate SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. The service can be found in a section of its own where you are able to view which domains are currently protected. For the ones which aren't, you can activate the SPF protection option and configure a variety of things during the process - the hostnames of the mail servers that are allowed to send messages from your mailboxes, the IPv4 and IPv6 addresses of the servers, and to create a rule that emails can be sent only when your domains use our MX records. The last mentioned choice is the most secure one, but it can be used if we handle the e-mail addresses for your domains and you are not using a different e-mail supplier. The newly created records will propagate within 24 hours and nobody will be able to forge the FROM field in an e-mail using your addresses.
