SPF, which means Sender Policy Framework, is an e-mail security system, that is designed to validate whether an email message was sent by an official server. Employing SPF protection for a given domain name will stop the counterfeiting of email addresses generated with the domain. In simple words: activating this feature for a domain generates a specific record in the Domain Name System (DNS) which includes the IP addresses of the servers which are permitted to send email messages from mailboxes under the domain. When this record propagates worldwide, it exists on all of the DNS servers that route the Internet traffic. When an email message is sent, the first DNS server it uses checks whether it originates from an authorized server. In the event it does, it's forwarded to the destination address, but when it does not originate from a server indexed in the SPF record for the domain, it is rejected. In this way nobody can mask an email address to make it look as if you are sending spam. This method is also referred to as email spoofing.

SPF Protection in Shared Hosting

You'll be able to enable the SPF protection option for your domains with just a few clicks from the Hepsia Control Panel, which is included with our shared hosting plans. This is performed from the section with an identical name and you can allow the protection for any domain part of our leading-edge cloud hosting platform. Using a very handy interface, all you'll have to type in is the hostname of the mail server that will be authorized to send out messages from your emails and its IPv4 or IPv6 address. Of course, you can add several servers too, if needed. In case your email addresses are taken care of by us, you may also take advantage of a more risk-free option by setting a restriction that e-mail messages can be sent only if your domains feature our MX records. This alternative cannot be used if your website is hosted with us, and your emails are with a third-party service provider. In either case, the SPF protection option will really improve your web security and prevent others from counterfeiting your email addresses.

SPF Protection in Semi-dedicated Servers

The Hepsia hosting Control Panel, that comes with all of our semi-dedicated plans, provides you with a really easy-to-use interface to enable the SPF protection service for any domain that you host inside your new account. A few clicks in the Emails section of Hepsia will be enough for that then you will only have to enter the hostname and the IP address of the mail server which will be allowed to send messages from your emails. When the e-mail messages are managed on our end and not by a different provider, you'll be able to boost the protection level even more and benefit from an option for all of the outgoing e-mail messages to be sent only if your domains include our MX records. This option provides you with increased control and it'll eliminate any chance of someone forging your e-mails with the objective of spamming and scamming people. It's not applicable in case only your web site is on our advanced cloud web hosting platform, while your e-mail addresses are handled by a different provider. If you aren't sure what features to select, our technical support staff will assist you 24/7.
