SPF, which is short for Sender Policy Framework, is an email security system, which is used to validate whether an e-mail message is sent by an authorized server. Employing SPF protection for a given domain will prevent the forging of email addresses made with the domain. In simple words: enabling this feature for a domain makes a special record in the Domain Name System (DNS) that contains the IP addresses of the servers which are allowed to send email messages from mail boxes under the domain. As soon as this record propagates globally, it will exist on all DNS servers that route the Internet traffic. Whenever a new e-mail message is sent, the first DNS server it uses verifies whether it comes from an approved server. When it does, it is sent to the destination address, yet when it does not originate from a server indexed in the SPF record for the domain, it's rejected. In this way nobody will mask an e-mail address and make it look as if you are e-mailing spam messages. This approach is also identified as email spoofing.
SPF Protection in Website Hosting
When you host your domain names in a website hosting account on our end and we handle the email addresses for them, you'll be able to enable SPF protection for them with several clicks inside your Hepsia Control Panel. This service can be found in a separate section where you'll be able to see which domains are already secured. For the ones that aren't, you'll be able to activate the SPF protection service and configure a number of things at the same time - the hostnames of the mail servers that are permitted to send messages from your mailboxes, the IPv4 and IPv6 addresses of the servers, and to set a rule that emails can be sent only when your domains use our MX records. The last mentioned option is the most secure one, and it can be used if we take care of the e-mail addresses for your domain names and do not use another email supplier. The newly created records will be activated within a day and nobody will be able to fake the FROM field in an email with your email addresses.
SPF Protection in Semi-dedicated Servers
The SPF protection function is provided with all the semi-dedicated servers, so in case you host your domain names in an account on our cloud web hosting platform, you can use this particular service easily for any of your domains. The Hepsia Control Panel, which comes as standard with the semi-dedicated accounts, features a very intuitive interface, therefore you won't have to be tech-savvy to secure your email addresses. You'll only need to type the hostname and the IP of each mail server that you would like to be allowed to send out e-mails from your addresses and immediately after that the new record will be active for the domain that you have chosen. As an additional option, we also allow you to limit your outgoing emails and secure your mailboxes further by allowing e-mail messages to be sent only if the domain in question features our MX records i.e. the e-mail messages for the domain should be managed here and not by some other supplier. Thus you will enjoy even superior control and there won't be any chance for anyone to fake your e-mails for malicious objectives.
