SPF, which is short for Sender Policy Framework, is an email security system, which is employed to verify if an email message was sent by an authorized server. Using SPF protection for a domain will prevent the faking of email addresses generated with the domain. In simple words: enabling this attribute for a domain generates a special record in the Domain Name System (DNS) which includes the IP addresses of the servers which are allowed to send e-mails from mailboxes using the domain. When this record propagates globally, it exists on all of the DNS servers that route the Internet traffic. Every time a new email message is sent, the first DNS server it uses checks whether it originates from an authorized server. In the event it does, it's forwarded to the destination address, yet if it does not originate from a server indexed in the SPF record for the domain, it's rejected. In this way nobody will be able to mask an e-mail address to make it look as if you're distributing spam messages. This method is also termed email spoofing.
SPF Protection in Cloud Website Hosting
SPF protection can be enabled for each domain hosted in a cloud website hosting account on our cloud hosting platform with no more than a few clicks. The feature is accessible in the Emails section of our innovative Hepsia Control Panel and all you need to use it is to pick one of your domain names from a drop-down menu and type in the hostnames plus the IPv4 or IPv6 addresses of the e-mail servers that will be permitted to send messages from your email addresses. As an additional option you can also restrict the messages to be sent from your domain name only if it includes our MX records, in other words when our servers handle the emails for it, not some third-party supplier. This solution offers you the best standard of security, but it's not applicable if only your website is on our servers while your email addresses for the domain are taken care of somewhere else. Either way, the SPF protection service will keep your emails secure from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Hosting
The Hepsia website hosting Control Panel, that is included with our Linux semi-dedicated hosting, will provide you with an exceptionally easy-to-use interface to activate the SPF security service for every domain name that you host inside your new account. A couple of clicks in the Emails section of Hepsia are enough for that then you'll only have to enter the hostname and the IP address of the mail server that will be allowed to send messages from your email addresses. In case the email messages are handled on our end and not by some other supplier, you're able to increase the security level even more and benefit from an option for all of the outgoing email messages to be sent only if your domains feature our MX records. This option gives you increased control and it will eliminate any chance of anyone forging your email addresses with the intention of spamming and / or scamming people. It is not applicable if just your website is on our innovative cloud website hosting platform, while your e-mails are managed by a different service provider. If you are not sure what options to choose, our tech support staff will assist you 24/7.
