SPF, which stands for Sender Policy Framework, is an email safety system, that is used to verify whether an e-mail message was sent by a certified server. Employing SPF protection for a particular domain will prevent the faking of email addresses made with the domain. In simple words: activating this function for a domain name creates a specific record in the Domain Name System (DNS) which includes the IP addresses of the servers that are permitted to send emails from mail boxes using the domain. The moment this record propagates globally, it exists on all DNS servers that direct the Internet traffic. Whenever a new e-mail message is sent, the initial DNS server it uses checks whether it originates from an accredited server. In the event it does, it's forwarded to the destination address, however when it does not come from a server listed in the SPF record for the particular domain, it's rejected. In this way nobody will be able to mask an email address and make it look as if you are e-mailing spam messages. This technique is also termed email spoofing.
SPF Protection in Shared Web Hosting
SPF protection can be activated for any domain hosted in a shared web hosting account on our cloud hosting platform with no more than a couple of clicks. The option is available in the Emails section of our exceptional Hepsia Control Panel and what is needed to activate it is to pick one of your domain names from the drop-down menu and to type in the hostnames as well as the IPv4 or IPv6 addresses of the email servers that will be approved to send messages from your emails. As an added option you may also restrict the emails to be sent from your domain only when it has our MX records, i.e. if our servers handle the e-mail addresses for it, not a third-party provider. This solution provides you with the highest degree of safety, but it is not applicable if only your web site is on our servers while the email addresses for the domain name are managed elsewhere. In either case, the SPF protection service will keep your email addresses secure from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Hosting
If you have a semi-dedicated server account with us, you are able to protect your emails by activating the SPF protection service for every domain name in the account with just a couple of mouse-clicks. You can do this in the Emails section of the Hepsia Control Panel which is provided with the semi-dedicated accounts and even when you have no previous experience with these kinds of things, you won't have any kind of trouble to activate the protection. All that you'll have to do is to find a domain from a drop-down menu and then type in the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your e-mail addresses will be delivered worldwide only if they are sent from that specific server. In case your email addresses are handled by us and not by some third-party provider, you can also use an option for emails to be sent only if the domain name includes our MX records and the latter is the most secure option. If you have any kind of questions regarding thisfunction, you can contact our technical support crew 24/7.
