Sender Policy Framework, or SPF, is a verification system, that is used to prevent the so-called e-mail spoofing where an e-mail message can be sent from one address, but to appear as being sent from a different, generally with the idea to fraud the recipient someway. If SPF protection is enabled for a domain, an exclusive record is created for it in the Domain Name System and all DNS servers globally receive it. The record contains all of the e-mail servers that are allowed to send valid messages from an address within the domain. When an email is sent, the first DNS server it encounters checks the SPF record and in case the sending server is permitted, the message is forwarded to the targeted receiver. In case, however, the sending server doesn't exist in the SPF record for the specified domain, the message won't be forwarded and it'll be discarded. In the event that you use this solution, it will stop third parties from sending spam e-mails which appear to have been sent from you.
SPF Protection in Shared Website Hosting
SPF protection can be enabled for every domain name hosted in a shared website hosting account on our cloud hosting platform with no more than a couple of mouse-clicks. The function can be found in the Emails section of our leading-edge Hepsia Control Panel and all you need to use it is to choose one of your domain names from a drop-down menu and to type in the hostnames plus the IPv4 or IPv6 addresses of the email servers that will be permitted to send email messages from your emails. As an added option you may also restrict the email messages to be sent from your domain name only if it includes our MX records, i.e. when our servers manage the email addresses for it, not some third-party supplier. This solution will give you the highest degree of security, but it is not applicable in case only your website is on our servers while your emails for the domain are managed in a different place. Regardless, our SPF protection service will keep your email addresses risk-free from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Hosting
The SPF protection function is available with all the Linux semi-dedicated hosting, so in case you host your domains in an account on our cloud website hosting platform, you will be able to use this service effortlessly for all of your domains. The Hepsia Control Panel, which comes with the semi-dedicated accounts, has a very easy to work with interface, so you don't need to be proficient in the use of computers in order to secure your e-mail addresses. You'll only have to type the hostname and the IP address of each mail server that you would like to be certified to send emails from your addresses and immediately after that the updated record will be activated for the domain name that you have chosen. As a further option, we will also give you the ability to restrict your outgoing emails and secure your mailboxes even better by allowing emails to be sent only if the domain name in question features our MX records i.e. the emails for the domain need to be managed here and not by some other supplier. By doing so you'll have even superior control and there won't be any chance for anyone to counterfeit your e-mails for harmful activities.
