Sender Policy Framework, or SPF, is a verification system, that is designed to prevent the so-called e-mail spoofing where an e-mail message is sent from one email address, but to look as being sent from a different, usually with the idea to fraud the recipient for some reason. If SPF protection is activated for a domain name, a unique record is generated for it in the Domain Name System and all of the DNS servers globally have it. The record includes all of the email servers that are allowed to send authentic messages from an address under the domain. When an e-mail is sent, the very first DNS server it encounters verifies the SPF record and if its sending server is permitted, the message is sent to the target receiver. When, however, the sending server is not included in the SPF record for the specified domain, the message won't be submitted and it will be discarded. In the event that you use this service, it will stop third parties from sending spam which look as if they have been sent by 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 platform with no more than a few mouse-clicks. The feature is accessible in the Emails section of our advanced Hepsia Control Panel and all it takes to enable it is to select one of your domain names from a drop-down menu and to enter the hostnames as well as the IPv4 or IPv6 addresses of the email servers that will be permitted to send email messages from your emails. As an additional option you may also restrict the e-mails to be sent from your domain only when it includes our MX records, i.e. if our servers handle the emails for it, not some third-party supplier. This feature provides you with the best level of safety, but it's not applicable when only your web site is on our servers while the email addresses for the domain name are handled in another place. Either way, the SPF protection service will keep your emails protected from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Servers
The SPF protection feature comes with all of the semi-dedicated plans, so when you host your domains in an account on our cloud hosting platform, you are able to activate this service without difficulty for all your domain names. The Hepsia Control Panel, which is included with the semi-dedicated accounts, offers a really user-friendly interface, therefore you will not need to be proficient in the use of computers to secure your emails. You will simply have to type the hostname and the IP address of each mail server that you'd like to be authorized to send e-mails from your addresses and shortly after that the new record will be active for the domain that you've picked. As a further option, we will also allow you to restrict the outgoing emails and secure your mailboxes even better by permitting e-mail messages to be sent only when the domain involved features our MX records i.e. the emails for the domain should be taken care of by us and not by another company. Doing so you'll enjoy even superior control and there won't be a chance for anybody to counterfeit your e-mail addresses for harmful intentions.
