SPF, which stands for Sender Policy Framework, is an email safety system, that is used to validate whether an email message was sent by an authorized server. Using SPF protection for a particular domain name will stop the faking of email addresses generated with the domain. In simple words: activating this attribute for a domain name makes a particular record in the Domain Name System (DNS) containing the IP addresses of the servers which are allowed to send e-mail messages from mailboxes using the domain. Once this record propagates globally, it will exist on all the DNS servers that direct the Internet traffic. Every time a new e-mail message is sent, the first DNS server it uses checks whether it comes from an authorized server. If it does, it's forwarded to the destination address, yet if it does not originate from a server indexed in the SPF record for the domain, it's rejected. Thus nobody will be able to mask an email address and make it appear as if you are distributing spam messages. This approach is also termed email spoofing.

SPF Protection in Shared Web Hosting

If you host your domains in a shared web hosting account with us and we manage the email addresses for them, you are able to enable SPF protection for them with a couple of clicks in your Hepsia Control Panel. This service is available in a separate section where you'll be able to see which domains are currently secured. For the ones that are not, you will be able to enable the SPF protection service and manage a lot of things during the process - the hostnames of the mail servers that are allowed to send messages from your e-mails, the IPv4 and IPv6 addresses of the servers, as well as to create a rule that messages can be sent only if your domain names have our MX records. The last solution is the most secure one, and you can use it if we manage the e-mails for your domain names and you're not using a different e-mail supplier. The newly created records will propagate within 1 day and nobody will be able to forge the FROM field in a message by using your addresses.

SPF Protection in Semi-dedicated Hosting

If you have a semi-dedicated server account with us, you will be able to secure your emails by enabling the SPF security service for every domain hosted in the account with only a couple of 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 things, you won't have any troubles to activate the security. Everything that you will have to do will be to choose a domain name from a drop-down list and after that type the mail server hostname and IPv4 or IPv6 address. The moment the updated record propagates, messages from your email addresses will be mailed globally only if they are sent from that particular server. When your emails are managed by our company and not by some third-party supplier, you will also be able to take advantage of an option for emails to be mailed only when the domain has our MX records and the aforementioned would be the most secure option. When you have any kind of questions related to thisfunction, you'll be able to contact our support team 24/7.
