Sender Policy Framework, or SPF, is a validation system, which is used to prevent the so-called email spoofing where an email message can be sent from one e-mail address, but to look as being sent from another, generally with the idea to fraud the recipient someway. When SPF protection is activated for a domain, an exclusive record is generated for it in the Domain Name System and all DNS servers globally have it. The record contains all mail servers that are allowed to send valid messages from an address under the domain. When an e-mail is sent, the very first DNS server it goes to checks the SPF record and when the sending server is permitted, the message is forwarded to the targeted receiver. When, 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'll be removed. In the event that you employ this solution, it'll prevent third parties from sending spam e-mails that seem to have been sent by you.

SPF Protection in Cloud Website Hosting

When you host your domain names in a cloud website hosting account on our end and we handle the emails for them, you'll be able to enable SPF protection for any of them with a few clicks in your Hepsia Control Panel. The service is available in its own section where you'll be able to view which domain names are already secured. For the ones that are not, you can enable the SPF protection service and manage a lot of things during the process - the hostnames of the mail servers that are permitted to send messages from your email addresses, the IPv4 and IPv6 addresses of these servers, and to create a rule that email messages can be sent only if your domains use our MX records. The last mentioned choice is the most secure one, and you can use it if we manage the email addresses for your domain names and do not use another e-mail service provider. The newly created records will propagate within one day and nobody will be able to forge the FROM field in a message by using your email addresses.
