Sender Policy Framework, or SPF, is a validation system, which is employed to stop the so-called e-mail spoofing where an e-mail message is sent from one email address, but to seem as being sent from another, often with the objective to scam the recipient someway. If SPF protection is activated for a domain, an exclusive record is created for it in the Domain Name System and all of the DNS servers globally receive it. The record includes all the email servers that are permitted to send valid messages from an e-mail address within the domain. When a message is sent, the very first DNS server it encounters checks the SPF record and when the sending server is permitted, the message is forwarded to the targeted destination. When, however, the sending server doesn't exist in the SPF record for the specified domain, the e-mail message will not be submitted and it'll be discarded. Whenever you employ this solution, it will prevent third parties from sending spam emails which look as if they have been sent from you.

SPF Protection in Cloud Website Hosting

When you host your domain names in a cloud website hosting account with us and we handle the e-mail addresses for them, you will be able to enable SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. The service can be found in its own section where you will be able to view which domain names are currently secured. For those that aren't, you can activate the SPF protection option and set up a variety of things in the process - the hostnames of the mail servers that are allowed to send messages from your addresses, the IPv4 and IPv6 addresses of these servers, as well as to create a rule that email messages can be sent only if your domains have our MX records. The last mentioned solution is the most secure one, and it can be used when we manage the email addresses for your domains and you're not using another email provider. The new records will be activated within 24 hours and nobody will be able to fake the FROM field in a message by using your e-mail addresses.

SPF Protection in Semi-dedicated Servers

When you have a semi-dedicated server account from our company, you can protect your email addresses by activating the SPF protection service for every domain name in your account with only a couple of mouse-clicks. This can be done through the Emails section of our Hepsia Control Panel that is included with the semi-dedicated accounts and even when you have no previous experience with these matters, you will not have any troubles to enable the security. The only things that you will need to do is to find a domain name from a drop-down menu then type the mail server hostname and IPv4 or IPv6 address. When the new record propagates, messages from your emails will be delivered globally only if they were sent from that particular server. If your emails are managed by us and not by a third-party provider, you will also be able to use an option for emails to be sent only when the domain has our MX records and the aforementioned would be the most secure option. In case you have any kind of questions regarding thisfunction, you can get in touch with our tech support team 24/7.
