SPF, which is an acronym for Sender Policy Framework, is an e-mail safety system, that is used to validate whether an e-mail message is sent by a licensed server. Employing SPF protection for a given domain will prevent the counterfeiting of emails created with the domain. In layman's terms: enabling this function for a domain generates a special record in the Domain Name System (DNS) that contains the IP of the servers that are allowed to send e-mails from mailboxes under the domain. The moment this record propagates globally, it will exist on all of the DNS servers that route the Internet traffic. When an e-mail message is sent, the initial DNS server it uses tests if it originates from an official server. When it does, it is forwarded to the destination address, however if it does not originate from a server part of the SPF record for the particular domain, it is rejected. Thus nobody will mask an e-mail address and make it appear as if you are e-mailing spam messages. This technique is also known as email spoofing.

SPF Protection in Semi-dedicated Servers

When you have a semi-dedicated server account from our company, you are able to secure your emails by enabling the SPF protection service for any domain in your account with only a couple of mouse-clicks. This is done in the Emails section of the Hepsia Control Panel that comes with the semi-dedicated accounts and even in case you have no previous practical experience with these things, you will not have any difficulties to enable the protection. All that you'll have to do will be to choose a domain name from a drop-down list and then type the mail server hostname and IPv4 or IPv6 address. When the updated record propagates, messages from your e-mail addresses will be mailed worldwide only if they were sent from that specific server. When your emails are handled by us and not by a third-party supplier, you will also be able to benefit from an option for e-mail messages to be mailed only when the domain includes our MX records and this is the safest option. When you have any kind of questions about thisfeature, you will be able to get in touch with our tech support team 24/7.
