SPF, which is short for Sender Policy Framework, is an email protection system, that is designed to validate whether an e-mail message was sent by a licensed server. Employing SPF protection for a domain will prevent the faking of email addresses generated with the domain. In layman's terms: activating this function for a domain name generates a specific record in the Domain Name System (DNS) that contains the IP of the servers which are allowed to send e-mails from mail boxes under the domain. As soon as this record propagates globally, it will exist on all the DNS servers that route the Internet traffic. Any time an e-mail message is sent, the first DNS server it goes through tests if it originates from an approved server. If it does, it's forwarded to the destination address, however if it doesn't come from a server listed in the SPF record for the particular domain, it is discarded. Thus nobody will be able to mask an email address and make it appear as if you're sending spam messages. This technique is also identified as email spoofing.
SPF Protection in Cloud Website Hosting
If you host your domains in a cloud website hosting account on our end and we handle the email addresses for them, you'll be able to enable SPF protection for any of them with several clicks in your Hepsia Control Panel. This service is available in a section of its own where you'll be able to view which domains are already secured. For those that aren't, you'll be able to enable the SPF protection option and manage various things at the same time - the hostnames of the mail servers that are permitted to send messages from your e-mails, the IPv4 and IPv6 addresses of the servers, as well as to set a rule that messages can be sent only if your domain names have our MX records. The aforementioned solution is the most secure one, and it can be used in the event that we manage the emails for your domain names and do not use a different email supplier. The new records will be activated within a day and nobody will be able to forge the FROM field in an email using your email addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account with us, you are able to protect your emails by activating the SPF security service for every domain in your account with only a few mouse-clicks. You can do this through the Emails section of the Hepsia Control Panel which is provided with the semi-dedicated accounts and even if you lack previous experience with these issues, you will not have any kind of troubles to activate the protection. The only things that you will need to do will be to choose a domain name from a drop-down menu and then type the mail server hostname and IPv4 or IPv6 address. Once the updated record propagates, messages from your e-mail addresses will be mailed worldwide only if they were sent from that particular server. When your e-mail addresses are handled by us and not by some third-party supplier, you can also benefit from an option for emails to be sent only when the domain name includes our MX records and the aforementioned would be the most secure option. When you have any kind of questions about thisfunction, you'll be able to contact our tech support crew 24/7.
