Sender Policy Framework, or SPF, is a verification system, that is employed to prevent the so-called email spoofing where an e-mail message can be sent from one email, but to appear as being sent from a different one, often with the objective to scam the recipient in some way. If SPF protection is enabled for a domain name, a specific record is generated for it in the Domain Name System and all the DNS servers globally receive it. The record includes all of the email servers that are allowed to send authentic messages from an email address part of the domain. When an e-mail is sent, the first DNS server it goes to verifies the SPF record and when the sending server is permitted, the message is sent to the target receiver. When, however, the sending server is not present in the SPF record for the specified domain, the email message will not be forwarded and it will be removed. In the event that you use this service, it will prevent third parties from sending spam e-mails which look as if they have been sent from you.
SPF Protection in Shared Web Hosting
The SPF protection feature is available as standard with every single shared web hosting plan that we offer and you're able to use it with ease to secure the e-mail addresses for each domain name hosted in your account. The service is controlled from the Emails section of our innovative, albeit easy-to-use Hepsia Control Panel. All you need to enable the protection is to type the IP of the mail server as well as its hostname - mail.server.com, for instance. Once the protection is activated, only this server will be able to send messages from emails made under the domain that you have picked. Your email addresses may be handled by some other company, but if we handle them together with your web site, you can also activate an option for emails to be sent only if the domain has our MX records. This selection provides you with improved protection as exclusively our server will be certified to send out messages from your mailboxes and you will have improved control. When you have any kind of questions or if you have any sort of difficulties with this service, you'll be able to contact our technical support crew anytime and they will help you right away.
