Sender Policy Framework, or SPF, is a verification system, that is designed to prevent the so-called e-mail spoofing where an email message is sent from one e-mail address, but to appear as being sent from another, usually with the objective to scam the recipient in some way. If SPF protection is enabled for a domain name, an exclusive record is made for it in the Domain Name System and all DNS servers globally have it. The record features all the e-mail servers that are allowed to send authentic messages from an address within the domain. When a message is sent, the first DNS server it encounters checks the SPF record and when the sending server is permitted, the message is forwarded to the targeted destination. When, however, the sending server doesn't exist in the SPF record for the given domain, the email message won't be sent and it will be discarded. Whenever you use this service, it will stop third parties from sending spam emails that seem to have been sent from you.

SPF Protection in Hosting

When you host your domain names in a hosting account on our end and we handle the email addresses for them, you'll be able to activate SPF protection for them with several clicks in your Hepsia Control Panel. This service is available in a section of its own where you will be able to see which domain names are already protected. For those that aren't, you can enable the SPF protection option and manage a variety of things during the process - the hostnames of the mail servers that are permitted to send messages from your e-mails, the IPv4 and IPv6 addresses of these servers, and even to create a rule that email messages can be sent only when your domains use our MX records. The aforementioned solution is the most secure one, and you can use it in the event that we take care of the emails for your domains and you're not using another email provider. The newly created records will propagate within one day and nobody will be able to fake the FROM field in a message using your email addresses.

SPF Protection in Semi-dedicated Hosting

If you have a semi-dedicated server account with us, you can protect your email addresses by activating the SPF security service for every domain name in the account with just a couple of mouse-clicks. This can be done from the Emails section of the Hepsia Control Panel that is provided with the semi-dedicated accounts and even if you lack previous practical experience with these matters, you will not have any kind of trouble to enable the security. Everything that you will need to do is to select a domain from a drop-down menu and after that type the mail server hostname and IPv4 or IPv6 address. When the new record propagates, messages from your emails will be delivered globally only if they were sent from that particular server. In case your e-mail addresses are taken care of by us and not by some third-party supplier, you'll also be able to benefit from an option for emails to be sent only when the domain name has our MX records and this is the safest option.
