Sender Policy Framework, or SPF, is a verification system, which is designed to prevent the so-called e-mail spoofing where an e-mail message is sent from one address, but to appear as being sent from a different, often with the idea to fraud the recipient someway. When SPF protection is activated for a domain, a special record is made for it in the Domain Name System and all DNS servers around the world receive it. The record features all email servers that are allowed to send authentic messages from an address part of the domain. When an email is sent, the very first DNS server it goes to verifies the SPF record and if its sending server is permitted, the message is sent to the target destination. When, however, the sending server is not contained in the SPF record for the specified domain, the e-mail message will not be forwarded and it will be removed. When you use this solution, it will prevent third parties from sending spam e-mails which seem to have been sent by you.

SPF Protection in Cloud Web Hosting

When you host your domains in a cloud web hosting account on our end and we manage the e-mails for them, you are able to activate SPF protection for any of them with several clicks in your Hepsia Control Panel. This service is available in a section of its own where you'll be able to view which domain names are already secured. For those that are not, you'll be able to enable the SPF protection solution and configure various things in the process - the hostnames of the mail servers that are allowed to send messages from your email addresses, the IPv4 and IPv6 addresses of these servers, as well as to set a rule that messages can be sent only when your domains include our MX records. The aforementioned solution is the most secure one, and it can be used if we take care of the e-mail addresses for your domain names and you are not using a different email supplier. The newly generated records will propagate within one day and nobody will be able to fake the FROM field in an e-mail using your addresses.

SPF Protection in Semi-dedicated Hosting

The Hepsia hosting Control Panel, which is included with our Linux semi-dedicated hosting, offers you a really easy-to-use interface to enable the SPF protection service for each domain that you host in your new account. Just a few clicks in the Emails section of Hepsia are enough for that then you will only have to enter the hostname and the IP address of the mail server that will be permitted to send out messages from your e-mail addresses. If the emails are taken care of on our end and not by another supplier, you're able to raise the protection level even further and benefit from an option for your outgoing emails to be sent only if your domain names feature our MX records. This option provides you with increased control and it'll eliminate any possibility of anyone forging your e-mail addresses with the intention of spamming and / or scamming people. It's not applicable if only your web site is on our hi-tech cloud website hosting platform, while your emails are handled by another service provider. If you aren't sure what options to choose, our technical support team will help you 24/7.
