Sender Policy Framework, or SPF, is a verification system, which is designed to stop the so-called e-mail spoofing where an email message can be sent from one e-mail, but to look as being sent from a different, often with the idea to fraud the recipient for some reason. If SPF protection is enabled for a domain name, a specific record is generated for it in the Domain Name System and all the DNS servers worldwide get it. The record features all mail servers that are allowed to send legitimate messages from an e-mail address under the domain. When a message is sent, the first DNS server it goes to checks the SPF record and in case the sending server is permitted, the message is forwarded to the target receiver. In case, however, the sending server is not contained in the SPF record for the given domain, the message will not be submitted and it will be discarded. In case you employ this solution, it will prevent third parties from sending spam that seem to have been sent from you.
SPF Protection in Cloud Hosting
SPF protection can be activated for any domain hosted in a cloud hosting account on our cloud platform with only a few mouse-clicks. The option is accessible in the Emails section of our advanced Hepsia Control Panel and what is needed to use it is to pick one of your domains from the drop-down list and enter the hostnames as well as the IPv4 or IPv6 addresses of the e-mail servers which will be certified to send messages from your email addresses. As an additional option you can also restrict the e-mails to be sent from your domain name only when it has our MX records, in other words when our servers manage the emails for it, not some third-party provider. This solution offers you the highest level of security, but it is not applicable when only your website is on our servers while the email addresses for the domain name are handled somewhere else. Regardless, our SPF protection service will keep your emails safe from being used for spam and scam purposes.
