Sender Policy Framework, or SPF, is a verification system, which is intended to prevent the so-called email spoofing where an e-mail message is sent from one e-mail, but to look as being sent from a different, usually with the idea to fraud the recipient someway. When SPF protection is activated for a domain name, a unique record is generated for it in the Domain Name System and all the DNS servers worldwide get it. The record includes all email servers that are permitted to send legitimate messages from an e-mail address within the domain. When an email is sent, the first DNS server it goes to verifies the SPF record and in case its sending server is authorized, the message is sent to the targeted destination. If, however, the sending server is not present in the SPF record for the specified domain, the email message won't be forwarded and it'll be discarded. Whenever you use this service, it'll prevent third parties from sending spam e-mails which look as if they have been sent from you.
SPF Protection in Shared Web Hosting
SPF protection can be enabled for any domain hosted in a shared web hosting account on our cloud hosting platform with only a few mouse-clicks. The feature can be found in the Emails section of our exceptional Hepsia Control Panel and what is needed to activate it is to pick one of your domain names from a drop-down list and type in the hostnames plus the IPv4 or IPv6 addresses of the e-mail servers that will be certified to send emails from your emails. As an added option you can also restrict the messages 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 a third-party supplier. This option provides you with the top level of protection, but it's not applicable if only your web site is on our servers while your email addresses for the domain name are handled elsewhere. In either case, the SPF protection service will keep your email addresses protected from being used for spam and/or scam purposes.
