Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called e-mail spoofing where an email message is sent from one email, but to look as being sent from a different one, often with the idea to fraud the recipient in some way. If SPF protection is activated for a domain, a specific record is made for it in the Domain Name System and all of the DNS servers globally have it. The record includes all of the email servers that are permitted to send legitimate messages from an email address under the domain. When an e-mail is sent, the first DNS server it encounters checks the SPF record and if the sending server is permitted, the message is sent to the targeted destination. When, however, the sending server is not included in the SPF record for the given domain, the message will not be forwarded and it will be discarded. When you use this solution, it'll stop third parties from sending spam messages which seem to have been sent from you.

SPF Protection in Shared Hosting

When you host your domains in a shared hosting account with us and we handle the e-mail addresses for them, you will be able to activate SPF protection for them with a few clicks inside your Hepsia Control Panel. This service is accessible in a separate section where you'll be able to see which domain names are currently protected. For those that aren't, you can enable the SPF protection solution and manage numerous things during the process - the hostnames of the mail servers that are permitted to send messages from your e-mails, the IPv4 and IPv6 addresses of these servers, and to create a rule that email messages can be sent only when your domains have our MX records. The aforementioned solution is the most secure one, but you can use it in the event that we handle the emails for your domains and you are not using another e-mail provider. The newly created records will be activated within one day and nobody will be able to fake the FROM field in an email with your e-mail addresses.
