SPF, which means Sender Policy Framework, is an email safety system, that is is intended to validate whether an email message was sent by an authorized server. Employing SPF protection for a particular domain will stop the forging of emails made with the domain. In simple words: activating this function for a domain name generates a special record in the Domain Name System (DNS) which includes the IP of the servers that are allowed to send emails from mailboxes using the domain. Once this record propagates worldwide, it exists on all of the DNS servers that route the Internet traffic. Whenever some e-mail message is sent, the first DNS server it goes through checks if it comes from an accredited server. When it does, it's sent to the destination address, however if it doesn't come from a server part of the SPF record for the particular domain, it's discarded. In this way nobody will be able to mask an email address then make it look as if you are sending spam messages. This approach is also called email spoofing.
SPF Protection in Web Hosting
The SPF protection function is provided by default with each web hosting plan that we supply and you can use it without difficulty to protect the email addresses for any domain hosted as part of your account. The service is operated from the Emails section of our hi-tech, albeit intuitive Hepsia Control Panel. All you need to enable the protection is to type in the IP address of the e-mail server and its hostname - mail.server.com, for example. As soon as the protection is activated, only this server will be able to send email messages from email addresses generated under the domain that you have selected. Your e-mail addresses can be managed by some other company, but when we manage them in addition to your site, you can also activate an option for your emails to be sent only when the domain uses our MX records. This option will provide you with superior protection as exclusively our server will be approved to send e-mails from your mailboxes and you'll have better control. When you have any kind of questions or in case you experience any problems with this service, you can contact our technical support team at any time and they will assist you right away.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account from our company, you are able to protect your emails by activating the SPF protection service for every domain hosted in your account with just a few mouse-clicks. This is done in the Emails section of our Hepsia Control Panel that is provided with the semi-dedicated accounts and even if you have no previous practical experience with these kinds of things, you will not have any kind of troubles to activate the security. All that you'll have to do will be to select a domain name from a drop-down menu then type in the mail server hostname and IPv4 or IPv6 address. As soon as the updated record propagates, messages from your emails will be sent globally only if they are sent from that server. When your email addresses are taken care of by our company and not by a third-party supplier, you will also be able to benefit from an option for e-mail messages to be sent only when the domain name includes our MX records and the aforementioned 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.
