SPF, which is an acronym for Sender Policy Framework, is an email safety system, that is is intended to confirm whether an email message was sent by a certified server. Using SPF protection for a given domain name will prevent the faking of email addresses created with the domain. In simple words: activating this function for a domain creates a specific record in the Domain Name System (DNS) that contains the IP of the servers which are allowed to send emails from mailboxes under the domain. When this record propagates worldwide, it exists on all of the DNS servers that route the Internet traffic. When a new email message is sent, the initial DNS server it uses checks if it originates from an approved server. When it does, it is sent to the destination address, but if it doesn't originate from a server indexed in the SPF record for the domain, it's discarded. Thus nobody will be able to mask an e-mail address and make it appear as if you are sending spam messages. This method is also called email spoofing.
SPF Protection in Cloud Hosting
SPF protection can be activated for every domain name hosted in a cloud hosting account on our cloud hosting platform with no more than a few mouse-clicks. The option can be found in the Emails section of our exceptional Hepsia Control Panel and what is needed to enable it is to pick one of your domain names from the drop-down list and enter the hostnames together with the IPv4 or IPv6 addresses of the e-mail servers which will be permitted to send emails from your email addresses. As an additional option you can also restrict the messages to be sent from your domain name only when it includes our MX records, in other words when our servers handle the emails for it, not a third-party supplier. This feature will provide you with the best standard of safety, but it is not applicable in case only your site is on our servers while the emails for the domain are managed elsewhere. In either case, the SPF protection service will keep your email addresses secure from being used for spam and/or scam purposes.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account with us, you are able to protect your emails by activating the SPF security service for any domain hosted in your account with just a few mouse-clicks. You can do this from the Emails section of our Hepsia Control Panel which is provided with the semi-dedicated accounts and even if you have no previous practical experience with such issues, you won't have any problems to activate the security. Everything that you will have to do will be to select a domain name from a drop-down menu and then type the mail server hostname and IPv4 or IPv6 address. The moment the updated record propagates, messages from your emails will be delivered around the world only if they were sent from that server. If your email addresses are managed by us and not by a third-party supplier, you can also take advantage of an option for emails to be mailed only if the domain name includes our MX records and this is the safest option. In case you have any questions about thisfeature, you will be able to get in touch with our technical support team 24/7.
