SPF, which stands for Sender Policy Framework, is an e-mail security system, which is employed to confirm if an email message is sent by a licensed server. Using SPF protection for a given domain will stop the forging of emails generated with the domain. In simple words: enabling this feature for a domain generates a particular record in the Domain Name System (DNS) which contains the IP of the servers which are permitted to send e-mails from mailboxes under the domain. The moment this record propagates globally, it will exist on all of the DNS servers that route the Internet traffic. Every time a new email message is sent, the first DNS server it goes through verifies whether it comes from an accredited server. In the event it does, it's sent to the destination address, but if it doesn't come from a server indexed in the SPF record for the domain, it's rejected. Thus nobody can mask an email address and make it appear as if you are distributing spam. This technique is also referred to as email spoofing.
SPF Protection in Shared Web Hosting
SPF protection can be activated for each domain name hosted in a shared web hosting account on our cloud platform with only a few clicks. The feature is accessible in the Emails section of our amazing Hepsia Control Panel and what is needed to enable it is to choose one of your domains from a drop-down list and type in the hostnames and the IPv4 or IPv6 addresses of the email servers that will be authorized to send email messages from your emails. As an additional option you can even restrict the e-mails to be sent from your domain name only if it includes our MX records, in other words when our servers manage the email addresses for it, not some third-party provider. This option will provide you with the best degree of safety, but it is not applicable in case only your site is on our servers while the emails for the domain name are handled in another place. Either way, our SPF protection service will keep your emails safe from being used for spam or scam purposes.
SPF Protection in Semi-dedicated Servers
The SPF protection function comes with all of the semi-dedicated servers, so when you host your domains in an account on our cloud hosting platform, you will be able to use the service with ease for all of your domain names. The Hepsia Control Panel, which comes as standard with the semi-dedicated accounts, features a very user-friendly interface, which means that you do not need to be tech-savvy to secure your email addresses. You will 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 shortly after that the new record will be activated for the domain name that you've chosen. As an additional option, we also allow you to limit your outgoing e-mail messages and secure your mailboxes even further by permitting emails to be sent only when the domain in question contains our MX records i.e. the e-mail messages for the domain name should be taken care of on our end and not by a different company. Thus you will get even superior control and there will not be any chance for someone to forge your e-mail addresses for harmful intentions.
