Sender Policy Framework, or SPF, is a validation system, that is intended to prevent the so-called email spoofing where an e-mail message can be sent from one e-mail, but to seem as being sent from a different, frequently with the idea to fraud the recipient in some way. When SPF protection is activated for a domain, a unique record is made for it in the Domain Name System and all DNS servers globally receive it. The record features all the email servers that are allowed to send legitimate messages from an e-mail address under the domain. When an email is sent, the very first DNS server it goes to verifies the SPF record and if the sending server is authorized, the message is forwarded to the targeted receiver. When, however, the sending server is not contained in the SPF record for the specified domain, the message won't be sent and it will be discarded. Whenever you use this service, it'll stop third parties from sending spam messages which look as if they have been sent from you.

SPF Protection in Web Hosting

SPF protection can be enabled for each domain name hosted in a web hosting account on our cloud platform with only a few clicks. The function is available in the Emails section of our leading-edge Hepsia Control Panel and what is needed to use it is to pick one of your domain names from a drop-down list and enter the hostnames along with the IPv4 or IPv6 addresses of the email servers which will be certified to send email messages from your email addresses. As an additional option you can also restrict the messages to be sent from your domain only if it has our MX records, i.e. if our servers handle the e-mail addresses for it, not a third-party supplier. This solution provides you with the top level of security, but it is not applicable if only your website is on our servers while your email addresses for the domain are managed somewhere else. Either way, our SPF protection service will keep your email addresses safe from being used for spam and/or scam purposes.

SPF Protection in Semi-dedicated Servers

The SPF protection function is available with all the semi-dedicated servers, so in case you host your domains in an account on our cloud website hosting platform, you can activate this particular service effortlessly for any of your domain names. The Hepsia Control Panel, which comes as standard with the semi-dedicated accounts, has a very user-friendly interface, so you do not need to be tech-savvy to protected your emails. You will simply need to type the hostname and the IP of each mail server that you'd like to be permitted to send emails from your addresses and right after that the new record will be activated for the domain name that you have chosen. As an additional option, we will also give you the ability to limit the outgoing email messages and secure your mailboxes further by permitting messages to be sent only when the domain name involved features our MX records i.e. the emails for the domain name have to be taken care of on our end and not by another company. In this way you'll enjoy even superior control and there won't be a chance for any person to fake your email addresses for harmful objectives.
