SPF, which is short for Sender Policy Framework, is an e-mail security system, which is designed to confirm whether an e-mail message is sent by an official server. Using SPF protection for a given domain will prevent the counterfeiting of emails generated with the domain. In layman's terms: enabling this attribute for a domain name creates a particular record in the Domain Name System (DNS) containing the IP of the servers that are allowed to send e-mails from mailboxes using the domain. When this record propagates worldwide, it exists on all of the DNS servers that direct the Internet traffic. Every time a new e-mail message is sent, the first DNS server it goes through verifies whether it originates from an approved server. When it does, it's sent to the destination address, however if it doesn't originate from a server indexed in the SPF record for the domain, it is rejected. In this way nobody will be able to mask an e-mail address and make it appear as if you're e-mailing spam. This technique is also called email spoofing.

SPF Protection in Shared Hosting

You'll be able to enable the SPF protection service for your domain names with a couple of clicks inside the Hepsia Control Panel, which is included in all our Linux shared hosting services. This is done through the section bearing the same name and you'll be able to enable the protection for any domain part of our outstanding cloud hosting platform. Using a really simple interface, all you'll have to submit is the hostname of the mail server which will be authorized to send out messages from your emails and its IPv4 or IPv6 address. Of course, it is possible to add several servers too, when needed. In case your e-mails are managed by us, you may also use a more secure option by setting a restriction that e-mails can be sent only when your domain names feature our MX records. This alternative can't be used when your web site is hosted here, and your emails are with a third-party supplier. Either way, the SPF protection option will significantly enhance your online safety and prevent other people from forging your e-mail addresses.

SPF Protection in Semi-dedicated Hosting

If you have a semi-dedicated server account from us, you will be able to secure your email addresses by activating the SPF security service for every domain in the account with only a few clicks. You can do this from the Emails section of our Hepsia Control Panel that is included with the semi-dedicated accounts and even if you lack previous experience with these kinds of things, you will not have any kind of troubles to activate the protection. All that you will need to do is to pick a domain from a drop-down menu then type in the mail server hostname and IPv4 or IPv6 address. Once the new record propagates, messages from your e-mail addresses will be mailed globally only if they're sent from that particular server. If your email addresses are managed by us and not by some third-party provider, you will also be able to activate an option for email messages to be sent only if the domain name contains our MX records and the aforementioned would be the safest option. If you have any questions related to thisfeature, you will be able to get in touch with our support crew 24/7.
