SPF, which means Sender Policy Framework, is an email security system, which is designed to confirm whether an e-mail message was sent by an authorized server. Employing SPF protection for a domain name will stop the counterfeiting of email addresses generated with the domain. In layman's terms: activating this feature for a domain creates a special record in the Domain Name System (DNS) that contains the IP of the servers that are allowed to send e-mails from mail boxes under the domain. As soon as this record propagates worldwide, it exists on all the DNS servers that route the Internet traffic. When a new e-mail message is sent, the initial DNS server it goes through verifies if it comes from an official server. If it does, it is sent to the destination address, but if it does not come from a server indexed in the SPF record for the particular domain, it's discarded. Thus nobody will mask an email address then make it look as if you are distributing spam. This method is also called email spoofing.
SPF Protection in Hosting
SPF protection can be enabled for any domain name hosted in a hosting account on our cloud platform with just a few clicks. The function can be found in the Emails section of our advanced Hepsia Control Panel and all you need to use it is to choose one of your domains from the drop-down list and then type in the hostnames and the IPv4 or IPv6 addresses of the e-mail servers which will be authorized to send email messages from your emails. As an added option you can also restrict the e-mails to be sent from your domain name only when it has our MX records, i.e. when our servers manage the email addresses for it, not some third-party provider. This option will give you the best degree of protection, but it's not applicable when only your site is on our servers while your email addresses for the domain name are taken care of in a different place. Either way, the SPF protection service will keep your email addresses secure from being used for spam or scam purposes.
SPF Protection in Semi-dedicated Servers
The SPF protection function is available with all semi-dedicated servers, so when you host your domains in an account on our cloud website hosting platform, you can use this service easily for all of your domain names. The Hepsia Control Panel, which is included with the semi-dedicated accounts, features a very user-friendly interface, which means that you do not have to be proficient in the use of computers in order to secure your email addresses. You'll simply need to type the hostname and the IP of each mail server that you would like to be permitted to send out e-mails from your addresses and right after that the new record will be activated for the domain name that you have selected. As an extra option, we will also allow you to restrict the outgoing email messages and secure your mailboxes even further by permitting messages to be sent only when the domain involved includes our MX records i.e. the e-mail messages for the domain have to be taken care of by us and not by a different company. By doing so you will have even better control and there will not be any chance for anyone to counterfeit your email addresses for malicious activities.
