Sender Policy Framework, or SPF, is a verification system, which is used to stop the so-called e-mail spoofing where an email message can be sent from one email, but to appear as being sent from a different, often with the purpose to scam the recipient someway. When SPF protection is enabled for a domain name, a unique record is made for it in the Domain Name System and all DNS servers around the world get it. The record includes all of the e-mail 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 goes to checks the SPF record and when its sending server is permitted, the message is forwarded to the target destination. In case, however, the sending server is not included in the SPF record for the particular domain, the message will not be submitted and it'll be removed. If you employ this solution, it will prevent third parties from sending spam e-mails which seem to have been sent from you.

SPF Protection in Cloud Website Hosting

If you host your domain names in a cloud website hosting account on our end and we manage the e-mail addresses for them, you'll be able to activate SPF protection for all of them with a few clicks in your Hepsia Control Panel. This service can be found in a section of its own where you are able to see which domains are already secured. For the ones that are not, you can enable the SPF protection solution and configure a number of things during the process - the hostnames of the mail servers that are permitted to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of these servers, and even to set a rule that email messages can be sent only when your domains have our MX records. The last solution is the most secure one, and you can use it in the event that we manage the e-mails for your domains and do not use some other email supplier. The newly generated records will propagate within 24 hours and nobody will be able to fake the FROM field in an email with your email addresses.

SPF Protection in Semi-dedicated Servers

When you have a semi-dedicated server account from us, you can protect your emails by enabling the SPF security service for every domain name hosted in your account with just a couple of mouse-clicks. You can do this in the Emails section of our Hepsia Control Panel which comes with the semi-dedicated accounts and even in case you have no previous experience with these kinds of things, you won't have any trouble to activate the security. All that you'll have to do is to select a domain from a drop-down list and then type the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your email addresses will be delivered globally only if they are sent from that server. In case your email addresses are managed by our company and not by a third-party provider, you'll also be able to take advantage of an option for emails to be sent only when the domain name features our MX records and the aforementioned would be the safest option. In case you have any kind of questions related to thisfeature, you'll be able to contact our support crew 24/7.
