Sender Policy Framework, or SPF, is a verification system, which is designed to prevent the so-called email spoofing where an e-mail message can be sent from one email address, but to appear as being sent from another one, frequently with the purpose to fraud the recipient in some way. If SPF protection is activated for a domain, a unique record is made for it in the Domain Name System and all of the DNS servers around the world have it. The record contains all e-mail servers that are permitted to send authentic messages from an e-mail address under the domain. When an email is sent, the first DNS server it encounters verifies the SPF record and in case its sending server is authorized, the message is forwarded to the target receiver. When, however, the sending server is not contained in the SPF record for the given domain, the email message will not be submitted and it will be removed. In the event that you employ this solution, it will stop third parties from sending spam messages which seem to have been sent by you.
SPF Protection in Shared Web Hosting
The SPF protection function is available as standard with each and every shared web hosting package that we supply and you can use it without any difficulty in order to secure the e-mails for each domain hosted in your account. The service is managed through the Emails section of the outstanding, and easy-to-use Hepsia Control Panel. What is needed to enable the protection is to type in the IP of the e-mail server as well as its hostname - mail.server.com, for instance. When the protection is activated, only this server will be able to send e-mails from emails made under the domain that you've selected. Your email addresses may be handled by some other provider, but if we handle them together with your website, you may also activate an option for your e-mail messages to be sent only when the domain uses our MX records. This selection provides you with even better protection as exclusively our server will be permitted to send out e-mail messages from your mailboxes and you will have better control. When you have any questions or if you experience any sort of troubles with this service, you can contact our technical support team anytime and they'll help you immediately.
