Sender Policy Framework, or SPF, is a verification system, which is employed to stop the so-called email spoofing where an email message can be sent from one email address, but to look as being sent from a different one, ordinarily with the idea to scam the recipient someway. If SPF protection is activated for a domain, an exclusive record is created for it in the Domain Name System and all the DNS servers around the world have it. The record includes all mail servers that are allowed to send legitimate messages from an e-mail address under the domain. When an email is sent, the first DNS server it encounters checks the SPF record and in case the sending server is permitted, the message is sent to the targeted destination. If, however, the sending server doesn't exist in the SPF record for the particular domain, the e-mail message will not be forwarded and it will be discarded. When you use this solution, it'll prevent third parties from sending spam emails which look as if they have been sent by you.

SPF Protection in Cloud Hosting

If you host your domain names in a cloud hosting account with us and we handle the e-mail addresses for them, you are able to activate SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. The service is accessible in its own section where you will be able to see which domain names are already secured. For the ones that aren't, you can enable the SPF protection service and configure numerous things during the process - the hostnames of the mail servers that are permitted to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of the servers, and to set a rule that email messages can be sent only when your domain names use our MX records. The aforementioned solution is the most secure one, and you can use it in the event that we handle the email addresses for your domain names and you are not using another email provider. The new records will propagate within 1 day and nobody will be able to forge the FROM field in a message with your e-mail addresses.
