SPF, which is an acronym for Sender Policy Framework, is an email protection system, that is used to validate whether an e-mail message is sent by an official server. Using SPF protection for a domain name will stop the forging of email addresses generated with the domain. In layman's terms: activating this function for a domain name makes a special record in the Domain Name System (DNS) which contains the IP of the servers which are allowed to send email messages from mailboxes under the domain. The moment this record propagates globally, it will exist on all of the DNS servers that direct the Internet traffic. Whenever an email message is sent, the first DNS server it goes through tests if it originates from an accredited server. In the event it does, it is forwarded to the destination address, but when it doesn't come from a server listed in the SPF record for the particular domain, it is rejected. In this way nobody can mask an e-mail address to make it look as if you're distributing spam. This technique is also called email spoofing.

SPF Protection in Shared Web Hosting

You are able to enable the SPF protection option for your domains with only a few clicks in the Hepsia Control Panel, which comes with our shared web hosting plans. This is performed via the section with an identical name and you'll be able to enable the protection for any domain on our exceptional cloud hosting platform. Using a really time and effort saving interface, all you'll have to type in is the hostname of the mail server which will be authorized to send messages from your e-mails and its IPv4 or IPv6 address. Of course, you can include several servers too, when needed. If your e-mails are taken care of on our end, you can also take advantage of an even more secure option by setting a restriction that e-mails can be sent only when your domains include our MX records. This option can't be used if your website is hosted here, and your email addresses are with a third-party supplier. Either way, the SPF protection solution will greatly enhance your web safety and stop others from forging your email addresses.

SPF Protection in Semi-dedicated Servers

If you have a semi-dedicated server account from our company, you can protect your email addresses by enabling the SPF protection service for any domain hosted in your account with only a couple of clicks. This is done in the Emails section of our Hepsia Control Panel which is included with the semi-dedicated accounts and even if you lack previous practical experience with these kinds of things, you won't have any kind of problems to enable the security. Everything that you will have to do is to pick a domain name from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. When the updated record propagates, messages from your emails will be delivered globally only if they were sent from that particular server. When your emails are managed by us and not by some third-party provider, you will also be able to activate an option for emails to be sent only when the domain name has our MX records and the aforementioned would be the safest option.
