SPF, which stands for Sender Policy Framework, is an email protection system, which is is intended to validate whether an email message was sent by an authorized server. Employing SPF protection for a particular domain name will stop the counterfeiting of emails made with the domain. In layman's terms: activating this attribute for a domain name creates a specific record in the Domain Name System (DNS) which includes the IP addresses of the servers that are permitted to send email messages from mail boxes under the domain. As soon as this record propagates worldwide, it will exist on all the DNS servers that route the Internet traffic. Every time an e-mail message is sent, the initial DNS server it uses verifies whether it originates from an accredited server. When it does, it's forwarded to the destination address, however if it doesn't come from a server indexed in the SPF record for the particular domain, it is discarded. In this way nobody will be able to mask an e-mail address to make it appear as if you are sending spam messages. This approach is also referred to as email spoofing.
SPF Protection in Shared Hosting
When you host your domain names in a shared hosting account on our end and we handle the email addresses for them, you'll be able to enable SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. This service can be found in a separate section where you will be able to see which domain names are already secured. For the ones which aren't, you'll be able to activate the SPF protection option and set up a number of things during the process - the hostnames of the mail servers that are allowed to send messages from your e-mails, the IPv4 and IPv6 addresses of the servers, and even to create a rule that messages can be sent only if your domain names include our MX records. The last mentioned option is the most secure one, but it can be used in the event that we take care of the e-mails for your domain names and do not use some other e-mail service provider. The newly created records will be activated within one day and nobody will be able to forge the FROM field in a message with your email addresses.
SPF Protection in Semi-dedicated Servers
The SPF protection function is available with all semi-dedicated hosting plans, so in case you host your domain names in an account on our cloud web hosting platform, you are able to use this service easily for all your domain names. The Hepsia Control Panel, which is included with the semi-dedicated accounts, offers a rather easy to work with interface, therefore you will not have to be tech-savvy to secure your e-mail addresses. You will only need to type the hostname and the IP of each mail server that you would like to be allowed to send out emails from your addresses and shortly after that the updated record will be active for the domain name that you have selected. As an extra option, we'll also allow you to control your outgoing emails and secure your mailboxes even further by allowing messages to be sent only if the domain involved contains our MX records i.e. the email messages for the domain have to be managed on our end and not by a different provider. By doing so you will get even better control and there won't be a chance for anyone to counterfeit your email addresses for harmful purposes.
