SPF, which means Sender Policy Framework, is an e-mail protection system, which is designed to validate whether an e-mail message was sent by an official server. Using SPF protection for a domain name will stop the faking of email addresses generated with the domain. In simple words: enabling this attribute for a domain creates a special record in the Domain Name System (DNS) which contains the IP addresses of the servers which are permitted to send emails from mailboxes under the domain. As soon as this record propagates globally, it exists on all DNS servers that direct the Internet traffic. Any time an e-mail message is sent, the first DNS server it goes through verifies whether it originates from an official server. If it does, it is sent to the destination address, yet if it does not originate from a server indexed in the SPF record for the domain, it's discarded. In this way nobody can mask an e-mail address then make it appear as if you are distributing spam. This approach is also referred to as email spoofing.
SPF Protection in Shared Hosting
If you host your domains in a shared hosting account on our end and we manage the email addresses for them, you are able to enable SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. This service is accessible in its own section where you can see which domain names are currently protected. For the ones that aren't, you will be able to enable the SPF protection option and configure a number of things during the process - the hostnames of the mail servers that are allowed to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of the servers, and to create a rule that email messages can be sent only when your domains use our MX records. The aforementioned option is the most secure one, but it can be used when we manage the e-mails for your domains and you're not using some other e-mail service provider. The new records will propagate within 24 hours and nobody will be able to fake the FROM field in an e-mail with your email addresses.
SPF Protection in Semi-dedicated Hosting
The Hepsia website hosting Control Panel, which comes with all of our semi-dedicated hosting, provides you with a very easy-to-use interface to activate the SPF protection service for any domain name that you host in your new account. A few clicks in the Emails section of Hepsia will be enough for that then you'll only have to enter the hostname and the IP address of the mail server which will be permitted to send out messages from your e-mails. In case the email messages are taken care of by us and not by a different provider, you are able to raise the security level even more and activate an option for the outgoing e-mail messages to be sent only if your domain names use our MX records. This option will provide you with increased control and it'll eliminate any chance of anybody faking your e-mails with the objective of spamming and / or scamming people. It's not applicable in case just your website is hosted on our innovative cloud web hosting platform, while your e-mail addresses are handled by some other service provider. If you aren't sure what options to select, our tech support crew will assist you 24/7.
