Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called email spoofing where an email message is sent from one address, but to look as being sent from another one, ordinarily with the objective to scam the recipient someway. When SPF protection is enabled for a domain name, a specific record is made for it in the Domain Name System and all the DNS servers worldwide get it. The record includes all email servers that are permitted to send valid messages from an e-mail address within the domain. When an email is sent, the first DNS server it goes to verifies the SPF record and in case the sending server is authorized, the message is sent to the target destination. When, however, the sending server is not contained in the SPF record for the specified domain, the e-mail message won't be submitted and it'll be removed. Whenever you use this solution, it'll stop third parties from sending spam that appear to have been sent by you.

SPF Protection in Cloud Hosting

If you host your domain names in a cloud hosting account with us and we handle the e-mail addresses for them, you will be able to activate SPF protection for any of them with a few clicks inside your Hepsia Control Panel. The service is available in a separate section where you'll be able to view which domain names are currently protected. For those that are not, you'll be able to enable the SPF protection solution and configure a number of things at the same time - the hostnames of the mail servers that are allowed to send messages from your e-mails, the IPv4 and IPv6 addresses of these servers, and even to set a rule that emails can be sent only when your domains have our MX records. The aforementioned solution is the most secure one, and you can use it if we manage the email addresses for your domains and do not use a different email provider. The newly created records will propagate within one day and nobody will be able to fake the FROM field in an email by using your addresses.

SPF Protection in Semi-dedicated Hosting

When you have a semi-dedicated server account with us, you can protect your emails by activating the SPF security service for every domain in your account with only a couple of clicks. This is done from the Emails section of the Hepsia Control Panel which is included with the semi-dedicated accounts and even in case you have no previous practical experience with these kinds of issues, you won't have any difficulties to enable the protection. All that you'll have to do is to find a domain from a drop-down menu and then type the mail server hostname and IPv4 or IPv6 address. When the updated record propagates, messages from your email addresses will be delivered globally only if they're sent from that server. If your emails are taken care of by our company and not by a third-party provider, you will also be able to take advantage of an option for email messages to be mailed only when the domain includes our MX records and the latter would be the safest option. If you have any kind of questions about thisfeature, you will be able to contact our support crew 24/7.
