SPF, which is an acronym for Sender Policy Framework, is an e-mail safety system, which is used to confirm whether an email message is sent by a licensed server. Employing SPF protection for a given domain will prevent the faking of email addresses created with the domain. In simple words: enabling this feature for a domain name creates a special record in the Domain Name System (DNS) which includes the IP of the servers which are permitted to send e-mail messages from mailboxes under the domain. Once this record propagates worldwide, it will exist on all of the DNS servers that route the Internet traffic. Every time an e-mail message is sent, the first DNS server it uses checks whether it comes from an official server. When it does, it is sent to the destination address, yet if it does not come from a server indexed in the SPF record for the domain, it is rejected. In this way nobody can mask an email address then make it look as if you're sending spam. This technique is also called email spoofing.
SPF Protection in Web Hosting
You'll be able to enable the SPF protection option for your domain names with just a few clicks from the Hepsia Control Panel, which is included with all our web hosting. This is performed through the section bearing the same name and you can allow the protection for each and every domain name part of our modern cloud hosting platform. Using a very intuitive interface, all you need to enter is the hostname of the mail server which will be approved to send messages from your e-mail addresses and its IPv4 or IPv6 address. Last, but not least, you're able to add several servers too, if needed. In case your email addresses are taken care of by us, you may also employ a more risk-free option by putting a limit that email messages can be sent only when your domains feature our MX records. This alternative cannot be used if your website is hosted here, but your e-mails are with some third-party supplier. In either case, the SPF protection solution will considerably increase your web security and prevent others from counterfeiting your email addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account from our company, you'll be able to secure your email addresses by enabling the SPF protection service for every domain hosted in the account with only a few mouse-clicks. This is done from the Emails section of the Hepsia Control Panel that comes with the semi-dedicated accounts and even if you have no previous experience with these kinds of issues, you won't have any troubles to activate the protection. Everything that you will need to do is to select a domain name from a drop-down menu and then type the mail server hostname and IPv4 or IPv6 address. Once the updated record propagates, messages from your e-mail addresses will be delivered around the world only if they are sent from that particular server. In case your emails are managed by our company and not by a third-party supplier, you can also benefit from an option for e-mail messages to be mailed only when the domain name includes our MX records and the latter would be the safest option. Should you have any kind of questions related to thisfeature, you'll be able to contact our technical support crew 24/7.
