SPF, which is an acronym for Sender Policy Framework, is an e-mail protection system, which is designed to confirm if an e-mail message is sent by an official server. Using SPF protection for a given domain will stop the faking of email addresses created with the domain. In layman's terms: enabling this function 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 email messages from mail boxes using the domain. The moment this record propagates worldwide, it exists on all of the DNS servers that direct the Internet traffic. When an email message is sent, the first DNS server it goes through checks whether it comes from an authorized server. When it does, it is sent to the destination address, but if it doesn't come from a server indexed in the SPF record for the domain, it is rejected. In this way nobody can mask an email address and make it look as if you are e-mailing spam. This technique is also identified as email spoofing.
SPF Protection in Shared Hosting
SPF protection can be activated for any domain hosted in a shared hosting account on our cloud hosting platform with just a couple of clicks. The function can be found in the Emails section of our revolutionary Hepsia Control Panel and what is needed to use it is to select one of your domains from a drop-down list and enter the hostnames and the IPv4 or IPv6 addresses of the email servers that will be approved to send emails from your email addresses. As an added option you may also restrict the email messages to be sent from your domain name only if it includes our MX records, in other words when our servers manage the email addresses for it, not some third-party supplier. This option provides you with the highest degree of security, but it is not applicable when only your site is on our servers while the emails for the domain are taken care of elsewhere. Either way, the SPF protection service will keep your email addresses safe from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Hosting
When 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 hosted in the account with only a few clicks. This can be done from the Emails section of our Hepsia Control Panel that is provided with the semi-dedicated accounts and even if you have no previous experience with such things, you will not have any difficulties to activate the protection. Everything that you'll need to do is to pick a domain from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. When the new record propagates, messages from your emails will be sent around the world only if they are sent from that server. If your emails are handled by us and not by some third-party supplier, you will also be able to take advantage of an option for e-mail messages to be sent only if the domain features our MX records and this would be the safest option.
