SPF, which stands for Sender Policy Framework, is an e-mail protection system, that is employed to validate whether an e-mail message is sent by a certified server. Using SPF protection for a domain name will stop the counterfeiting of emails generated with the domain. In layman's terms: enabling this attribute for a domain name makes a particular record in the Domain Name System (DNS) that contains the IP of the servers which are permitted to send emails from mailboxes using the domain. As soon as this record propagates worldwide, it exists on all DNS servers that route the Internet traffic. Any time a new email message is sent, the initial DNS server it goes through verifies if it originates from an accredited server. In the event it does, it's forwarded to the destination address, but when it does not 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 email address then make it look as if you're sending spam messages. This method is also known as email spoofing.
SPF Protection in Shared Hosting
When you host your domains in a shared hosting account with us and we handle the e-mail addresses for them, you will be able to activate SPF protection for all of them with a few clicks in your Hepsia Control Panel. The service can be found in a section of its own where you're able to view which domains are already protected. For those which aren't, you'll be able to enable the SPF protection solution and set up numerous things during this process - the hostnames of the mail servers that are allowed to send messages from your emails, the IPv4 and IPv6 addresses of these servers, and to create a rule that emails can be sent only when your domains include our MX records. The last solution is the most secure one, and it can be used if we take care of the e-mails for your domains and do not use some other e-mail service provider. The newly generated records will propagate within 1 day and nobody will be able to forge the FROM field in an e-mail by using your addresses.
SPF Protection in Semi-dedicated Hosting
The SPF protection function is available with all Linux semi-dedicated hosting packages, so when you host your domain names in an account on our cloud website hosting platform, you can use the service without difficulty for all your domain names. The Hepsia Control Panel, which is provided with the semi-dedicated accounts, features a very intuitive interface, which means that you won't have to be tech-savvy to protected your email addresses. You will only have to type the hostname and the IP of each mail server that you'd like to be authorized to send e-mails from your addresses and immediately after that the updated record will be activated for the domain that you have chosen. As an extra option, we'll also allow you to restrict the outgoing emails and secure your mailboxes even better by permitting messages to be sent only if the domain involved has our MX records i.e. the emails for the domain have to be taken care of here and not by some other supplier. Doing so you will have even superior control and there won't be any chances for someone to forge your e-mails for malicious activities.
