SPF, which means Sender Policy Framework, is an email protection system, which is designed to confirm if an email message is sent by an authorized server. Using SPF protection for a given domain name will stop the faking of email addresses created with the domain. In simple words: enabling this feature for a domain makes a specific record in the Domain Name System (DNS) which includes the IP of the servers which are permitted to send email messages from mailboxes using the domain. The moment this record propagates worldwide, it exists on all DNS servers that direct the Internet traffic. Whenever an e-mail message is sent, the initial DNS server it goes through tests if it comes from an accredited server. If it does, it's sent to the destination address, yet when it doesn't originate from a server part of the SPF record for the domain, it's discarded. Thus nobody can mask an email address and make it look as if you're sending spam messages. This approach is also known as email spoofing.

SPF Protection in Shared Website Hosting

If you host your domain names in a shared website hosting account on our end and we manage the e-mails for them, you are able to enable SPF protection for all of them with a couple of clicks in your Hepsia Control Panel. The service is available in its own section where you are able to view which domain names are currently secured. For the ones that are not, you can activate the SPF protection option and configure a lot of things at the same time - the hostnames of the mail servers that are allowed to send messages from your mailboxes, the IPv4 and IPv6 addresses of the servers, and even to set a rule that messages can be sent only when your domains use our MX records. The last choice is the most secure one, and it can be used in the event that we take care of the e-mail addresses for your domains and you're not using a different e-mail provider. The newly generated records will propagate within 24 hours and nobody will be able to forge the FROM field in a message by using your email addresses.

SPF Protection in Semi-dedicated Servers

If you have a semi-dedicated server account from our company, you can protect your email addresses by enabling the SPF security service for every domain in the account with only a couple of clicks. You can do this from the Emails section of our Hepsia Control Panel that is provided with the semi-dedicated accounts and even in case you have no previous experience with such things, you will not have any trouble to enable the security. The only things that you'll have to do is to find a domain from a drop-down list then type the mail server hostname and IPv4 or IPv6 address. As soon as the new record propagates, messages from your e-mail addresses will be mailed globally only if they're sent from that particular server. If your email addresses are managed by our company and not by some third-party provider, you can also activate an option for email messages to be mailed only when the domain contains our MX records and this would be the safest option. Should you have any kind of questions regarding thisfunction, you'll be able to contact our technical support crew 24/7.
