Sender Policy Framework, or SPF, is a validation system, which is employed to stop the so-called email spoofing where an e-mail message can be sent from one address, but to appear as being sent from a different one, generally with the objective to scam the recipient in some way. If SPF protection is enabled for a domain, a unique record is made for it in the Domain Name System and all of the DNS servers around the world get it. The record includes all mail servers that are permitted to send valid messages from an e-mail address within the domain. When a message is sent, the first DNS server it encounters checks the SPF record and when the sending server is authorized, the message is forwarded to the target destination. In case, however, the sending server is not present in the SPF record for the particular domain, the e-mail message won't be forwarded and it will be removed. If you use this solution, it'll prevent third parties from sending spam emails that seem to have been sent from you.

SPF Protection in Cloud Website Hosting

If you host your domains in a cloud website hosting account on our end and we manage the email addresses for them, you will be able to activate SPF protection for any of them with a few clicks in your Hepsia Control Panel. The service can be found in a separate section where you will be able to view which domain names are currently protected. For the ones that are not, you'll be able to enable the SPF protection service and configure a variety 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 domains include our MX records. The last choice is the most secure one, but it can be used in the event that we handle the email addresses for your domains and you're not using some other e-mail service provider. The new records will propagate within one day and nobody will be able to forge 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 our company, you'll be able to secure your emails by enabling the SPF protection service for any domain name in the account with only a few mouse-clicks. This is done in the Emails section of the Hepsia Control Panel that comes with the semi-dedicated accounts and even if you lack previous experience with such things, you will not have any kind of difficulties to activate the security. All that you will need to do is to pick a domain name from a drop-down list then type the mail server hostname and IPv4 or IPv6 address. When the new record propagates, messages from your email addresses will be mailed worldwide only if they were sent from that particular server. When your e-mail addresses are taken care of by us and not by some third-party supplier, you will also be able to activate an option for emails to be mailed only if the domain includes our MX records and this would be the safest option. In case you have any questions related to thisfunction, you'll be able to get in touch with our support team 24/7.
