Sender Policy Framework, or SPF, is a validation system, that is intended to prevent the so-called e-mail spoofing where an email message is sent from one e-mail, but to appear as being sent from a different one, ordinarily with the idea to scam the recipient for some reason. When SPF protection is activated for a domain name, an exclusive record is created for it in the Domain Name System and all the DNS servers globally get it. The record features all the email servers that are allowed to send legitimate messages from an address within the domain. When an e-mail is sent, the first DNS server it encounters verifies the SPF record and in case its sending server is permitted, the message is sent to the targeted destination. If, however, the sending server is not present in the SPF record for the specified domain, the message will not be sent and it'll be removed. If you use this solution, it'll prevent third parties from sending spam messages that look as if they have been sent from you.

SPF Protection in Cloud Web Hosting

If you host your domain names in a cloud web hosting account on our end and we manage the email addresses for them, you are able to enable SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. This service is available in a section of its own where you are able to see which domain names are currently secured. For the ones that aren't, you will be able to enable the SPF protection service and configure various things at the same time - the hostnames of the mail servers that are allowed to send messages from your email addresses, the IPv4 and IPv6 addresses of the servers, as well as to create a rule that email messages can be sent only when your domain names use our MX records. The aforementioned option is the most secure one, and it can be used if we take care of the e-mails for your domain names and you are not using some other e-mail supplier. The new records will be activated within 1 day and nobody will be able to fake the FROM field in an e-mail by using your e-mail addresses.

SPF Protection in Semi-dedicated Servers

The SPF protection feature is provided with all of the Linux semi-dedicated plans, so in case you host your domain names in an account on our cloud web hosting platform, you can activate the service with ease for all your domains. The Hepsia Control Panel, which comes with the semi-dedicated accounts, offers a rather user-friendly interface, which means that you don't have to be proficient in the use of computers to protected your e-mail addresses. You'll only need to type the hostname and the IP address of each mail server that you'd like to be allowed to send e-mails from your addresses and right after that the updated record will be active for the domain name that you've selected. As an extra option, we also allow you to limit your outgoing e-mail messages and protect your mailboxes further by allowing email messages to be sent only when the domain name involved includes our MX records i.e. the e-mail messages for the domain name need to be taken care of by us and not by a different company. In this way you'll get even superior control and there won't be any chance for anyone to forge your email addresses for harmful intentions.
