SPF, which is an acronym for Sender Policy Framework, is an email safety system, which is is intended to verify if an email message is sent by a certified server. Employing SPF protection for a particular domain name will prevent the faking of emails generated with the domain. In simple words: activating this feature for a domain name makes a special record in the Domain Name System (DNS) which includes the IP addresses of the servers that are allowed to send e-mails from mailboxes using the domain. As soon as this record propagates globally, it will exist on all the DNS servers that direct the Internet traffic. Any time some email message is sent, the first DNS server it uses tests if it originates from an authorized server. When it does, it is forwarded to the destination address, however if it does not originate from a server part of the SPF record for the particular domain, it is rejected. Thus nobody will mask an e-mail address and make it appear as if you are sending spam. This technique is also termed email spoofing.
SPF Protection in Shared Web Hosting
When you host your domains in a shared web hosting account on our end and we handle the e-mails for them, you will be able to activate SPF protection for any of them with a few clicks inside your Hepsia Control Panel. The service is available in a separate section where you're able to view which domains are currently protected. For those that are not, you can enable the SPF protection service and manage a variety of things in the process - the hostnames of the mail servers that are permitted to send messages from your e-mails, the IPv4 and IPv6 addresses of these servers, and even to set a rule that emails can be sent only when your domains use our MX records. The last mentioned option is the most secure one, and it can be used when we take care of the e-mails for your domains and you're not using some other e-mail provider. The newly generated records will be activated within 24 hours and nobody will be able to fake the FROM field in a message by using your e-mail addresses.
