Sender Policy Framework, or SPF, is a verification system, which is employed to prevent the so-called email spoofing where an email message is sent from one email, but to appear as being sent from another, generally with the purpose to fraud the recipient someway. If SPF protection is activated for a domain, a special record is made for it in the Domain Name System and all of the DNS servers globally receive it. The record contains all mail servers that are allowed to send legitimate messages from an e-mail address within the domain. When an email is sent, the very first DNS server it encounters verifies the SPF record and if its sending server is permitted, the message is forwarded to the targeted receiver. When, however, the sending server is not included in the SPF record for the given domain, the message won't be submitted and it'll be removed. If you use this service, it'll stop third parties from sending spam e-mails that seem to have been sent from you.
SPF Protection in Website Hosting
The SPF protection option is provided by default with each website hosting
package that we offer and you will be able to use it without any difficulty to protect the e-mail addresses for any domain name hosted in your account. The service is managed from the Emails section of the innovative, yet easy-to-use Hepsia Control Panel. All it takes to activate the protection is to type in the IP of the email server as well as its hostname - mail.server.com, for example. The moment the protection is activated, only this server will be able to send email messages from emails created under the domain that you've picked. Your e-mails may be handled by another company, but when we handle them together with your site, you can also activate the option for your messages to be sent only when the domain has our MX records. This feature provides you with even better security as solely our server will be approved to send out emails from your mailboxes and you will have improved control. When you have any kind of questions or in case you have any issues with this particular service, you can contact our technical support crew anytime and they'll help you immediately.

The SPF protection feature comes with all Linux semi-dedicated hosting service
, so when you host your domains in an account on our cloud web hosting platform, you can use the service easily for all of your domains. The Hepsia Control Panel, which comes as standard with the semi-dedicated accounts, has a really intuitive interface, therefore you do not have to be tech-savvy to secure your emails. You'll simply have to type the hostname and the IP address of each mail server that you would like to be permitted to send e-mails from your addresses and right after that the updated record will be active for the domain name that you've chosen. As an additional option, we will also give you the ability to limit the outgoing emails and secure your mailboxes further by allowing email messages to be sent only when the domain name in question features our MX records i.e. the email messages for the domain name have to be taken care of on our end and not by another provider. By doing this you will enjoy even superior control and there will not be any chance for somebody to forge your email addresses for malicious activities.
