SPF, which is short for Sender Policy Framework, is an email security system, that is designed to verify if an e-mail message was sent by an authorized server. Employing SPF protection for a given domain will prevent the forging of emails made with the domain. In layman's terms: enabling this attribute for a domain name makes a special record in the Domain Name System (DNS) which includes the IP of the servers that are permitted to send email messages from mailboxes using the domain. Once this record propagates worldwide, it exists on all the DNS servers that route the Internet traffic. Any time some e-mail message is sent, the first DNS server it goes through verifies whether it comes from an approved server. When it does, it's sent to the destination address, however when it does not come from a server indexed in the SPF record for the particular domain, it's rejected. Thus nobody will be able to mask an e-mail address and make it look as if you are distributing spam. This method is also called email spoofing.
SPF Protection in Web Hosting
The SPF protection function is accessible by default with each web hosting plan that we offer and you'll be able to use it without difficulty to secure the emails for any domain hosted as part of your account. The service is managed from the Emails section of our cutting-edge, albeit intuitive Hepsia Control Panel. All you need to activate the protection is to type in the IP address of the email server plus its hostname - mail.server.com, for example. When the protection is active, only this server will be able to send out emails from email addresses generated under the domain name that you've selected. Your emails may be taken care of by some other company, but when we manage them in addition to your site, you may also enable the option for e-mails to be sent only if the domain uses our MX records. This solution will provide you with better security as exclusively our server will be approved to send out e-mail messages from your mailboxes and you will have improved control. If you have any kind of questions or in case you have any sort of difficulties with this particular service, you can contact our technical support team anytime and they will assist you in a timely manner.
SPF Protection in Semi-dedicated Hosting
If you have a semi-dedicated server account with us, you'll be able to protect your emails by activating the SPF security service for every domain name in your account with just a couple of clicks. This is done through the Emails section of our Hepsia Control Panel that is included with the semi-dedicated accounts and even in case you have no previous experience with these things, you won't have any difficulties to enable the protection. All that you will need to do is to select a domain name from a drop-down menu then type the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your e-mail addresses will be sent around the world only if they were sent from that particular server. When your emails are taken care of by our company and not by a third-party supplier, you will also be able to take advantage of an option for e-mail messages to be mailed only if the domain name contains our MX records and the aforementioned is the safest option.
