Sender Policy Framework, or SPF, is a validation system, which is employed to prevent the so-called e-mail spoofing where an e-mail message is sent from one email, but to seem as being sent from a different one, often with the objective to fraud the recipient in some way. When SPF protection is activated for a domain name, a special record is generated for it in the Domain Name System and all DNS servers around the world have it. The record includes all of the email servers that are allowed to send valid messages from an email address under the domain. When a message is sent, the very first DNS server it encounters verifies the SPF record and if the sending server is permitted, the message is sent to the target receiver. In case, however, the sending server is not present in the SPF record for the particular domain, the email message won't be forwarded and it'll be discarded. Whenever you employ this service, it'll stop third parties from sending spam e-mails which seem to have been sent by you.
SPF Protection in Cloud Hosting
SPF protection can be enabled for each domain name hosted in a cloud hosting account on our cloud platform with no more than a few mouse-clicks. The feature is accessible in the Emails section of our outstanding Hepsia Control Panel and what is needed to enable it is to pick one of your domain names from a drop-down menu and enter the hostnames as well as the IPv4 or IPv6 addresses of the email servers which will be approved to send messages from your email addresses. As an added option you can even restrict the e-mails to be sent from your domain only when it has our MX records, i.e. when our servers handle the emails for it, not some third-party provider. This solution will provide you with the top level of protection, but it's not applicable in case only your site is on our servers while your emails for the domain name are managed in another place. In either case, the SPF protection service will keep your emails safe from being used for spam or scam purposes.
