Sender Policy Framework, or SPF, is a validation system, which is employed to stop the so-called e-mail spoofing where an email message is sent from one address, but to look as being sent from another one, typically with the objective to scam the recipient for some reason. When SPF protection is activated for a domain, a specific record is created for it in the Domain Name System and all the DNS servers globally have it. The record features all e-mail servers that are allowed to send valid messages from an address under the domain. When an email is sent, the very first DNS server it goes to checks the SPF record and if the sending server is authorized, the message is forwarded to the targeted destination. When, however, the sending server is not contained in the SPF record for the specified domain, the message won't be forwarded and it will be discarded. In case you employ this solution, it'll stop third parties from sending spam emails which appear to have been sent from you.
SPF Protection in Website Hosting
SPF protection can be activated for any domain hosted in a website hosting account on our cloud hosting platform with only a couple of mouse-clicks. The option can be found in the Emails section of our amazing Hepsia Control Panel and all it takes to enable it is to select one of your domains from the drop-down menu and to enter the hostnames as well as the IPv4 or IPv6 addresses of the e-mail servers which will be permitted to send email messages from your email addresses. As an additional option you can even restrict the messages to be sent from your domain name only when it has our MX records, in other words when our servers manage the emails for it, not some third-party supplier. This option provides you with the best degree of safety, but it is not applicable in case only your site is on our servers while the emails for the domain name are managed somewhere else. Either way, our SPF protection service will keep your emails protected from being used for spam or scam purposes.
SPF Protection in Semi-dedicated Hosting
The SPF protection feature is featured with all of the Linux semi-dedicated hosting, so when you host your domain names in an account on our cloud web hosting platform, you'll be able to activate this service easily for any of your domain names. The Hepsia Control Panel, which is provided with the semi-dedicated accounts, has a very intuitive interface, therefore you don't have to be tech-savvy to protected your email addresses. You will only need to type the hostname and the IP of each mail server that you'd like to be permitted to send out emails from your addresses and shortly after that the updated record will be activated for the domain that you've selected. As a further option, we also give you the ability to restrict the outgoing email messages and protect your mailboxes even better by allowing emails to be sent only when the domain in question features our MX records i.e. the e-mail messages for the domain have to be handled by us and not by a different provider. Thus you'll enjoy even superior control and there will not be any chance for somebody to forge your e-mail addresses for malicious intentions.
