SPF, which means Sender Policy Framework, is an e-mail security system, that is employed to verify if an e-mail message is sent by a certified server. Using SPF protection for a domain name will stop the forging of emails generated with the domain. In layman's terms: enabling this attribute for a domain creates a specific record in the Domain Name System (DNS) which includes the IP of the servers that are allowed to send email messages from mail boxes using the domain. The moment this record propagates worldwide, it will exist on all the DNS servers that direct the Internet traffic. When some e-mail message is sent, the initial DNS server it goes through verifies whether it comes from an authorized server. When it does, it is forwarded to the destination address, but when it doesn't come from a server indexed in the SPF record for the domain, it is discarded. Thus nobody can mask an e-mail address then make it appear as if you're e-mailing spam. This technique is also termed email spoofing.
SPF Protection in Website Hosting
You'll be able to enable the SPF protection option for your domain names with only a couple of clicks inside the Hepsia Control Panel, which comes with our Linux website hosting plans. This is performed through the section with the same name and you'll be able to set up the protection for each domain name hosted on our outstanding cloud platform. Using a very simple interface, all you'll have to submit is the hostname of the mail server which will be permitted to send messages from your emails and its IPv4 or IPv6 address. Of course, it is possible to include several servers as well, if needed. When your e-mails are taken care of by us, you can also employ a more secure option by putting a limit that e-mails can be sent only if your domains include our MX records. This option can't be applied in case your website is here, while your emails are with some third-party supplier. In either case, the SPF protection option can vastly enhance your online safety and prevent others from forging your e-mail addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account with us, you can secure your email addresses by enabling the SPF security service for every domain in the account with just a couple of mouse-clicks. This is done through the Emails section of the Hepsia Control Panel which comes with the semi-dedicated accounts and even when you have no previous experience with such matters, you won't have any kind of troubles to enable the protection. All that you'll need to do will be to find a domain from a drop-down list then type the mail server hostname and IPv4 or IPv6 address. When the new record propagates, messages from your e-mail addresses will be mailed worldwide only if they are sent from that particular server. When your email addresses are managed by us and not by a third-party supplier, you will also be able to benefit from an option for emails to be sent only if the domain name features our MX records and the aforementioned would be the most secure option. Should you have any questions related to thisfeature, you'll be able to contact our technical support crew 24/7.
