Sender Policy Framework, or SPF, is a validation system, that is used to prevent the so-called email spoofing where an e-mail message can be sent from one email, but to appear as being sent from another, ordinarily with the purpose to scam the recipient in some way. When SPF protection is activated for a domain, an exclusive record is made for it in the Domain Name System and all the DNS servers around the world have it. The record features all mail servers that are allowed to send legitimate messages from an email address under the domain. When an email is sent, the first DNS server it encounters checks the SPF record and in case its sending server is permitted, the message is sent to the target receiver. If, however, the sending server is not present in the SPF record for the specified domain, the e-mail message won't be submitted and it'll be removed. If you use this solution, it'll prevent third parties from sending spam e-mails which seem to have been sent from you.

SPF Protection in Cloud Website Hosting

SPF protection can be enabled for any domain hosted in a cloud website hosting account on our cloud hosting platform with just a couple of clicks. The feature is accessible in the Emails section of our innovative Hepsia Control Panel and all it takes to enable it is to choose one of your domains from a drop-down list and type in the hostnames plus the IPv4 or IPv6 addresses of the e-mail servers that will be certified to send email messages from your emails. As an additional option you can even restrict the emails to be sent from your domain only when it includes our MX records, i.e. if our servers handle the emails for it, not a third-party provider. This feature offers you the best standard of safety, but it's not applicable when only your site is on our servers while your email addresses for the domain name are managed elsewhere. In either case, our SPF protection service will keep your email addresses safe from being used for spam and scam purposes.

SPF Protection in Semi-dedicated Hosting

The SPF protection attribute is provided with all of the Linux semi-dedicated hosting services, so when you host your domains in an account on our cloud website hosting platform, you're able to use this particular service easily for all your domains. The Hepsia Control Panel, which comes as standard with the semi-dedicated accounts, features a really user-friendly interface, which means that you do not need to be tech-savvy in order to secure your e-mail addresses. You will simply have to type the hostname and the IP of each mail server that you'd like to be allowed to send emails from your addresses and immediately after that the new record will be active for the domain name that you've chosen. As a further option, we will also give you the ability to limit the outgoing emails and protect your mailboxes even further by permitting messages to be sent only if the domain name in question includes our MX records i.e. the e-mail messages for the domain need to be taken care of by us and not by a different provider. Doing so you'll get even better control and there will not be any chances for anyone to fake your e-mail addresses for harmful objectives.
