Sender Policy Framework, or SPF, is a validation system, which is used to prevent the so-called e-mail spoofing where an email message is sent from one address, but to look as being sent from another, frequently with the idea to fraud the recipient for some reason. If SPF protection is activated for a domain name, a special record is created for it in the Domain Name System and all the DNS servers globally get it. The record includes all the mail servers that are allowed to send legitimate messages from an address within the domain. When an e-mail is sent, the very first DNS server it goes to checks the SPF record and if the sending server is authorized, the message is forwarded to the targeted receiver. If, however, the sending server doesn't exist in the SPF record for the specified domain, the email message will not be sent and it will be removed. If you employ this solution, it'll stop third parties from sending spam that look as if they have been sent from you.

SPF Protection in Shared Web Hosting

When you host your domains in a shared web hosting account on our end and we handle the e-mail addresses for them, you'll be able to enable SPF protection for all of them with a couple of clicks in your Hepsia Control Panel. The service is available in its own section where you'll be able to see which domain names are already secured. For those which aren't, you can activate the SPF protection service and manage a lot of things during this process - the hostnames of the mail servers that are permitted to send messages from your emails, the IPv4 and IPv6 addresses of the servers, and even to set a rule that email messages can be sent only if your domain names have our MX records. The last solution is the most secure one, and it can be used in the event that we manage the e-mail addresses for your domains and do not use another email service provider. The newly generated records will be activated within 1 day and nobody will be able to forge the FROM field in a message by using your email addresses.
