SPF, which means Sender Policy Framework, is an email security system, that is employed to confirm whether an email message was sent by a licensed server. Employing SPF protection for a particular domain will stop the counterfeiting of email addresses generated with the domain. In simple words: activating this feature for a domain creates a special record in the Domain Name System (DNS) which contains the IP of the servers that are allowed to send e-mail messages from mail boxes under the domain. The moment this record propagates worldwide, it will exist on all of the DNS servers that direct the Internet traffic. When an e-mail message is sent, the first DNS server it uses verifies if it originates from an approved server. If it does, it's sent to the destination address, yet when it doesn't originate from a server listed in the SPF record for the particular domain, it's discarded. Thus nobody will mask an email address to make it look as if you're e-mailing spam. This technique is also identified as email spoofing.
SPF Protection in Semi-dedicated Hosting
The Hepsia hosting Control Panel, which is included with our semi-dedicated hosting services
, provides you with a really user-friendly interface to activate the SPF protection service for every domain that you host in your new account. A few clicks in the Emails section of Hepsia are enough for that and you'll only have to type in the hostname and the IP address of the mail server that will be allowed to send messages from your e-mails. If the email messages are handled by us and not by some other provider, you can raise the security level even more and enable an option for all the outgoing email messages to be sent only if your domains use our MX records. This option provides you with better control and it'll eliminate any chance of anybody faking your emails with the objective of spamming and / or scamming people. It is not applicable when just your site is hosted on our state-of-the-art cloud web hosting platform, while your e-mails are managed by another service provider. If you are not sure what features to pick, our technical support team will assist you 24/7.
