SPF, which is an acronym for Sender Policy Framework, is an email security system, that is used to confirm if an email message is sent by an authorized server. Employing SPF protection for a given domain name will prevent the faking of email addresses created with the domain. In simple words: enabling this feature for a domain name makes a particular record in the Domain Name System (DNS) containing the IP of the servers which are permitted to send emails from mailboxes using the domain. Once this record propagates worldwide, it exists on all of the DNS servers that direct the Internet traffic. Whenever a new email message is sent, the initial DNS server it goes through verifies whether it originates from an approved server. If it does, it's forwarded to the destination address, but when it doesn't originate from a server listed in 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're distributing spam. This technique is also identified as email spoofing.
SPF Protection in Cloud Website Hosting
SPF protection can be activated for each domain name hosted in a cloud website hosting account on our cloud platform with just a couple of mouse-clicks. The function is available in the Emails section of our amazing Hepsia Control Panel and all it takes to enable it is to pick one of your domains from a drop-down list and type in the hostnames together with the IPv4 or IPv6 addresses of the mail servers that will be approved to send messages from your email addresses. As an added option you can even restrict the messages to be sent from your domain name only when it includes our MX records, in other words if our servers manage the email addresses for it, not a third-party provider. This solution will provide you with the best level of protection, but it's not applicable if only your site is on our servers while the e-mail addresses for the domain name are managed in another place. Regardless, the SPF protection service will keep your email addresses risk-free from being used for spam or scam purposes.
SPF Protection in Semi-dedicated Hosting
The Hepsia website hosting Control Panel, which comes as standard with all our Linux semi-dedicated packages, provides you with an incredibly user-friendly interface to enable the SPF protection service for every domain that you host in your new account. Several clicks in the Emails section of Hepsia will be enough for that then you'll only have to enter the hostname and the IP address of the mail server that will be permitted to send out messages from your email addresses. If the e-mail messages are taken care of on our end and not by some other supplier, you will be able to increase the security level even more and take advantage of an option for the outgoing emails to be sent only if your domains use our MX records. This option will give you better control and it'll eliminate any chance of anyone faking your email addresses with the intention of spamming and scamming people. It is not applicable when just your web site is hosted on our state-of-the-art cloud hosting platform, while your e-mail addresses are managed by another provider. If you aren't sure what features to choose, our tech support team will assist you 24/7.
