Sender Policy Framework, or SPF, is a validation system, that is employed to stop the so-called e-mail spoofing where an e-mail message is sent from one email address, but to appear as being sent from another one, usually with the idea to scam the recipient for some reason. When SPF protection is enabled for a domain name, a specific record is created for it in the Domain Name System and all DNS servers worldwide have it. The record features all the mail servers that are permitted to send legitimate messages from an address under the domain. When a message is sent, the very first DNS server it goes to verifies the SPF record and in case the sending server is authorized, the message is forwarded to the target receiver. When, however, the sending server is not included in the SPF record for the specified domain, the message will not be forwarded and it'll be removed. If you employ this service, it'll prevent third parties from sending spam that appear to have been sent from you.

SPF Protection in Hosting

SPF protection can be activated for each domain hosted in a hosting account on our cloud hosting platform with just a few clicks. The option can be found in the Emails section of our exceptional Hepsia Control Panel and all it takes to enable it is to pick one of your domain names from a drop-down list and enter the hostnames along with the IPv4 or IPv6 addresses of the mail servers which will be authorized to send email messages from your emails. As an added option you can even restrict the e-mails to be sent from your domain name only if it has our MX records, i.e. if our servers manage the email addresses for it, not some third-party supplier. This solution will give you the best standard of security, but it is not applicable when only your web site is on our servers while the email addresses for the domain name are managed in another place. Either way, the SPF protection service will keep your emails risk-free from being used for spam and/or scam purposes.
