SPF, which stands for Sender Policy Framework, is an email security system, that is used to validate if an email message was sent by an official server. Using SPF protection for a given domain name will prevent the faking of email addresses generated with the domain. In simple words: enabling this feature for a domain makes a specific record in the Domain Name System (DNS) which contains the IP addresses of the servers that are allowed to send email messages from mailboxes under the domain. As soon as this record propagates globally, it exists on all of the DNS servers that direct the Internet traffic. Every time some e-mail message is sent, the initial DNS server it uses tests if it comes from an accredited server. When it does, it's forwarded to the destination address, however when it does not originate from a server indexed in the SPF record for the particular domain, it is discarded. Thus nobody will be able to mask an e-mail address to make it appear as if you are distributing spam messages. This technique is also identified as email spoofing.
SPF Protection in Cloud Hosting
SPF protection can be enabled for each domain hosted in a cloud hosting account on our cloud hosting platform with just a few mouse-clicks. The feature is available in the Emails section of our amazing Hepsia Control Panel and all it takes to use it is to pick one of your domains from a drop-down list and then type in the hostnames plus the IPv4 or IPv6 addresses of the e-mail servers which will be certified to send email messages from your email addresses. As an additional option you may also restrict the email messages to be sent from your domain only if it has our MX records, in other words when our servers manage the email addresses for it, not some third-party supplier. This solution provides you with the highest degree of security, but it is not applicable when only your site is on our servers while your emails for the domain are taken care of in another place. In either case, our SPF protection service will keep your email addresses protected from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Hosting
The Hepsia web hosting Control Panel, which comes as standard with our Linux semi-dedicated hosting packages, offers you an incredibly easy-to-use interface to enable the SPF protection service for every domain that you host within your new account. A couple of clicks in the Emails section of Hepsia will be enough for that then you'll only have to type in the hostname and the IP address of the mail server which will be allowed to send messages from your e-mails. In case the email messages are taken care of by us and not by another supplier, you will be able to boost the protection level even more and take advantage of an option for your outgoing emails to be sent only if your domain names feature our MX records. This option will give you better control and it'll eliminate any possibility of somebody faking your e-mails with the intention of spamming and scamming people. It is not applicable if just your site is on our cutting-edge cloud hosting platform, while your email addresses are managed by some other service provider. If you aren't sure what options to select, our tech support staff will assist you 24/7.
