Sender Policy Framework, or SPF, is a validation system, which is intended to stop the so-called e-mail spoofing where an e-mail message can be sent from one e-mail address, but to seem as being sent from a different, usually with the objective to fraud the recipient for some reason. When SPF protection is enabled for a domain name, a unique record is made for it in the Domain Name System and all the DNS servers globally have it. The record includes all of the e-mail servers that are allowed to send authentic messages from an email address part of the domain. When an e-mail is sent, the very first DNS server it encounters verifies the SPF record and if its sending server is permitted, the message is sent to the target receiver. When, however, the sending server is not contained in the SPF record for the particular domain, the e-mail message will not be sent and it'll be removed. In the event that you use this service, it'll stop third parties from sending spam which look as if they have been sent from you.

SPF Protection in Website Hosting

SPF protection can be activated for every domain hosted in a website hosting account on our cloud platform with only a few mouse-clicks. The option can be found in the Emails section of our modern Hepsia Control Panel and all you need to use it is to pick one of your domains from the drop-down menu and then enter the hostnames plus the IPv4 or IPv6 addresses of the mail servers which will be approved to send emails from your email addresses. As an added option you can even restrict the emails to be sent from your domain only if it includes our MX records, i.e. if our servers handle the email addresses for it, not some third-party provider. This option will provide you with the best level of security, but it's not applicable when only your website is on our servers while your email addresses for the domain name are taken care of in a different place. Either way, our SPF protection service will keep your email addresses safe from being used for spam and scam purposes.

SPF Protection in Semi-dedicated Hosting

The SPF protection feature is available with all Linux semi-dedicated hosting packages, so if you host your domain names in an account on our cloud website hosting platform, you will be able to activate this service without difficulty for any of your domain names. The Hepsia Control Panel, which comes as standard with the semi-dedicated accounts, features a rather intuitive interface, therefore you don't have to be proficient in the use of computers in order to protected your emails. You'll only need to type the hostname and the IP address of each mail server that you'd like to be certified to send e-mails from your addresses and immediately after that the new record will be activated for the domain that you have chosen. As an additional option, we'll also give you the ability to restrict your outgoing emails and secure your mailboxes even further by allowing e-mail messages to be sent only if the domain involved features our MX records i.e. the emails for the domain name have to be handled by us and not by a different company. By doing so you will enjoy even superior control and there won't be any chances for someone to forge your e-mails for harmful uses.
