Sender Policy Framework, or SPF, is a verification system, that is used to stop the so-called email spoofing where an e-mail message is sent from one e-mail, but to appear as being sent from another one, frequently with the purpose to scam the recipient for some reason. When SPF protection is activated for a domain name, a special record is generated for it in the Domain Name System and all of the DNS servers around the world receive it. The record includes all the e-mail servers that are allowed to send valid messages from an e-mail address part of the domain. When an e-mail is sent, the very first DNS server it encounters checks the SPF record and when the sending server is authorized, the message is sent to the target receiver. If, however, the sending server is not contained in the SPF record for the given domain, the email message won't be forwarded and it will be removed. In case you employ this service, it will stop third parties from sending spam e-mails which appear to have been sent by you.

SPF Protection in Cloud Web Hosting

When you host your domain names in a cloud web hosting account with us and we handle the e-mail addresses for them, you are able to enable SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. This service can be found in a separate section where you can see which domain names are currently secured. For those which aren't, you will be able to activate the SPF protection option and set up numerous things at the same time - the hostnames of the mail servers that are allowed to send messages from your mailboxes, the IPv4 and IPv6 addresses of the servers, and to create a rule that messages can be sent only when your domain names use our MX records. The last choice is the most secure one, but you can use it if we handle the e-mails for your domains and you are not using some other e-mail supplier. The newly created records will be activated within one day and nobody will be able to fake the FROM field in a message using your e-mail addresses.
