Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called email spoofing where an e-mail message is sent from one email address, but to seem as being sent from another one, generally with the purpose to scam the recipient for some reason. If SPF protection is activated for a domain name, a unique record is generated for it in the Domain Name System and all of the DNS servers around the world have it. The record features all of the email servers that are permitted to send valid messages from an e-mail address within the domain. When an email is sent, the very first DNS server it encounters checks the SPF record and if its sending server is authorized, the message is forwarded to the targeted destination. When, however, the sending server is not present in the SPF record for the particular domain, the email message will not be submitted and it'll be removed. If you employ this solution, it'll prevent third parties from sending spam which appear to have been sent from you.

SPF Protection in Web Hosting

The SPF protection feature is available by default with every single web hosting package that we supply and you will be able to use it without any difficulty so as to protect the e-mails for any domain hosted as part of your account. The service is handled from the Emails section of our advanced, and easy-to-use Hepsia Control Panel. All you need to enable the protection is to type in the IP of the mail server plus its hostname - mail.server.com, for example. When the protection is active, only this server will be able to send out e-mail messages from e-mails created under the domain that you've selected. Your e-mails can be managed by a different provider, but if we handle them together with your site, you can enable the option for your email messages to be sent only if the domain has our MX records. This option will provide you with even better security as just our server will be authorized to send out e-mail messages from your mailboxes and you'll have superior control. If you have any kind of questions or in case you experience any problems with this service, you can contact our technical support team anytime and they'll help you right away.
