SPF, which stands for Sender Policy Framework, is an email protection system, which is designed to verify whether an email message is sent by an official server. Employing SPF protection for a particular domain name will prevent the counterfeiting of email addresses created with the domain. In layman's terms: activating this attribute for a domain name makes a special record in the Domain Name System (DNS) which contains the IP addresses of the servers that are allowed to send e-mail messages from mailboxes under the domain. Once this record propagates globally, it will exist on all DNS servers that route the Internet traffic. Every time a new e-mail message is sent, the initial DNS server it uses checks whether it originates from an approved server. When it does, it's forwarded to the destination address, yet when it does not originate from a server indexed in the SPF record for the domain, it is rejected. Thus nobody will be able to mask an e-mail address and make it appear as if you are e-mailing spam. This method is also called email spoofing.

SPF Protection in Cloud Hosting

When you host your domain names in a cloud hosting account on our end and we handle the email addresses for them, you will be able to activate SPF protection for any of them with several clicks inside your Hepsia Control Panel. The service is available in a section of its own where you are able to see which domains are already secured. For those that are not, you will be able to enable the SPF protection service and configure a lot of things during the process - the hostnames of the mail servers that are allowed to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of these servers, and even to set a rule that emails can be sent only when your domain names use our MX records. The last choice is the most secure one, and you can use it in the event that we manage the e-mails for your domain names and do not use another email supplier. The newly generated records will propagate within 1 day and nobody will be able to fake the FROM field in a message with your e-mail addresses.

SPF Protection in Semi-dedicated Servers

If you have a semi-dedicated server account from us, you can protect your emails by activating the SPF security service for every domain name hosted in the account with just a couple of clicks. This is done from the Emails section of the Hepsia Control Panel that is provided with the semi-dedicated accounts and even if you have no previous practical experience with these kinds of issues, you will not have any problems to activate the protection. All that you will have 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 updated record propagates, messages from your e-mail addresses will be sent around the world only if they are sent from that particular server. When your email addresses are managed by our company and not by some third-party supplier, you can also use an option for emails to be mailed only if the domain features our MX records and the aforementioned would be the most secure option. When you have any kind of questions regarding thisfeature, you will be able to get in touch with our technical support team 24/7.
