Sender Policy Framework, or SPF, is a verification system, which is used to prevent the so-called e-mail spoofing where an e-mail message can be sent from one address, but to look as being sent from another, generally with the purpose to fraud the recipient someway. When SPF protection is activated for a domain, a unique record is made for it in the Domain Name System and all of the DNS servers worldwide get it. The record includes all of the mail servers that are permitted to send valid messages from an email address part of the domain. When an e-mail 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 targeted receiver. When, however, the sending server is not contained in the SPF record for the specified domain, the message won't be submitted and it'll be discarded. If you use this service, it'll stop third parties from sending spam messages that seem to have been sent from you.

SPF Protection in Hosting

When you host your domain names in a hosting account on our end and we handle 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 is accessible in its own section where you will be able to view which domain names are currently protected. For those which aren't, you will be able to enable the SPF protection solution and manage a variety of things during the process - the hostnames of the mail servers that are permitted to send messages from your e-mails, the IPv4 and IPv6 addresses of these servers, and to create a rule that messages can be sent only if your domain names use our MX records. The aforementioned solution is the most secure one, and it can be used if we take care of the email addresses for your domains and do not use a different e-mail service provider. The new records will propagate within one day and nobody will be able to fake the FROM field in an email by using your email addresses.

SPF Protection in Semi-dedicated Hosting

When you have a semi-dedicated server account from us, you'll be able to secure your email addresses by activating the SPF protection service for every domain in your account with only a couple of mouse-clicks. This is done from the Emails section of our Hepsia Control Panel which comes with the semi-dedicated accounts and even if you have no previous practical experience with such issues, you will not have any trouble to enable the security. All that you'll need to do is to pick a domain from a drop-down list and after that type the mail server hostname and IPv4 or IPv6 address. Once the updated record propagates, messages from your email addresses will be mailed around the world only if they are sent from that server. In case your emails are managed by our company and not by a third-party provider, you can also benefit from an option for e-mail messages to be mailed only if the domain name contains our MX records and this is the safest option. In case you have any kind of questions regarding thisfunction, you will be able to get in touch with our tech support team 24/7.
