Sender Policy Framework, or SPF, is a verification system, that is designed to prevent the so-called email spoofing where an e-mail message is sent from one email address, but to appear as being sent from a different one, frequently with the purpose to scam the recipient someway. When SPF protection is enabled for a domain name, an exclusive record is generated for it in the Domain Name System and all DNS servers globally receive it. The record features all the e-mail servers that are permitted to send authentic messages from an address within the domain. When a message is sent, the first DNS server it encounters checks the SPF record and when 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 given domain, the e-mail message won't be sent and it will be removed. If you employ this solution, it will stop third parties from sending spam messages which appear to have been sent by you.

SPF Protection in Cloud Website Hosting

When you host your domains in a cloud website hosting account on our end and we manage the email addresses for them, you are able to enable SPF protection for them with a few clicks inside your Hepsia Control Panel. This service is available in a separate section where you'll be able to see which domain names are already protected. For the ones which aren't, you can enable the SPF protection service and configure a variety of things at the same time - the hostnames of the mail servers that are permitted to send messages from your mailboxes, the IPv4 and IPv6 addresses of these servers, and even to create a rule that emails can be sent only when your domains use our MX records. The last option is the most secure one, but you can use it if we handle the e-mails for your domain names and you are not using a different e-mail service provider. The new records will propagate within one day and nobody will be able to fake the FROM field in a message by using your e-mail addresses.
