Sender Policy Framework, or SPF, is a validation system, that is employed to stop the so-called e-mail spoofing where an email message can be sent from one address, but to look as being sent from a different one, generally with the objective to scam the recipient for some reason. When SPF protection is enabled for a domain name, an exclusive record is generated for it in the Domain Name System and all the DNS servers worldwide receive it. The record contains all the e-mail servers that are allowed to send valid messages from an e-mail address within the domain. When an email is sent, the first DNS server it encounters verifies the SPF record and when the sending server is authorized, the message is sent to the target receiver. When, however, the sending server is not contained in the SPF record for the given domain, the message won't be forwarded and it'll be removed. In case you employ this service, it will stop third parties from sending spam emails which seem to have been sent from you.
SPF Protection in Shared Hosting
SPF protection can be activated for any domain name hosted in a shared hosting account on our cloud hosting platform with only a couple of clicks. The feature is available in the Emails section of our state-of-the-art Hepsia Control Panel and all you need to use it is to choose one of your domains from a drop-down menu and then type in the hostnames together with the IPv4 or IPv6 addresses of the e-mail servers which will be certified to send emails from your emails. As an additional option you can even restrict the e-mails to be sent from your domain name only if it includes our MX records, i.e. if our servers manage the e-mail addresses for it, not a third-party supplier. This solution will provide you with the highest level of protection, but it is not applicable when only your site is on our servers while the email addresses for the domain are taken care of somewhere else. In either case, the SPF protection service will keep your emails secure from being used for spam or scam purposes.
