Sender Policy Framework, or SPF, is a verification system, which is designed to prevent the so-called email spoofing where an email message can be sent from one e-mail, but to seem as being sent from a different one, typically with the purpose to fraud the recipient for some reason. If SPF protection is enabled for a domain, a specific record is made for it in the Domain Name System and all of the DNS servers globally receive it. The record features all of the email servers that are permitted to send valid messages from an email address within the domain. When a message is sent, the very first DNS server it encounters checks the SPF record and when its sending server is permitted, the message is forwarded to the target destination. When, however, the sending server is not included in the SPF record for the specified domain, the message will not be sent and it will be removed. When you employ this solution, it'll prevent third parties from sending spam that seem to have been sent from you.

SPF Protection in Cloud Web Hosting

When you host your domains in a cloud web hosting account on our end and we handle the e-mails for them, you are able to activate SPF protection for any of them with a couple of clicks inside your Hepsia Control Panel. This service can be found in its own section where you can see which domains are currently secured. For those that aren't, you can activate the SPF protection option and manage a number of things at the same time - the hostnames of the mail servers that are allowed to send messages from your email addresses, the IPv4 and IPv6 addresses of these servers, and even to set a rule that email messages can be sent only if your domain names use our MX records. The last option is the most secure one, and you can use it if we take care of the emails for your domains and do not use a different e-mail supplier. The new records will propagate within 1 day and nobody will be able to fake the FROM field in an email using your email addresses.

SPF Protection in Semi-dedicated Hosting

If you have a semi-dedicated server account from our company, you will be able to protect your emails by activating the SPF security service for any domain hosted in the account with only a couple of mouse-clicks. This can be done through the Emails section of the Hepsia Control Panel that is included with the semi-dedicated accounts and even when you have no previous practical experience with such issues, you will not have any troubles to activate the security. All that you will have to do is to select a domain from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. The moment the updated record propagates, messages from your e-mail addresses will be sent worldwide only if they are sent from that server. In case your e-mail addresses are managed by our company and not by some third-party supplier, you'll also be able to benefit from an option for emails to be sent only when the domain name has our MX records and the aforementioned is the safest option. In case you have any kind of questions regarding thisfunction, you will be able to get in touch with our technical support team 24/7.
