Sender Policy Framework, or SPF, is a validation system, which is used to prevent the so-called email spoofing where an email message can be sent from one address, but to appear as being sent from a different one, generally with the objective to fraud the recipient for some reason. If SPF protection is activated for a domain, an exclusive record is generated for it in the Domain Name System and all the DNS servers worldwide receive it. The record contains all e-mail servers that are allowed to send authentic messages from an email address under the domain. When an e-mail is sent, the first DNS server it goes to verifies the SPF record and if the sending server is permitted, the message is forwarded to the targeted destination. In case, however, the sending server is not contained in the SPF record for the specified domain, the message won't be forwarded and it will be removed. If you use this solution, it'll stop third parties from sending spam e-mails which seem to have been sent from you.
SPF Protection in Shared Website Hosting
SPF protection can be enabled for each domain hosted in a shared website hosting account on our cloud platform with only a couple of mouse-clicks. The option can be found in the Emails section of our cutting-edge Hepsia Control Panel and what is needed to activate it is to pick one of your domain names from a drop-down menu and to type in the hostnames together with the IPv4 or IPv6 addresses of the email servers which will be authorized to send email messages from your emails. As an added option you may also restrict the messages to be sent from your domain name only when it has our MX records, i.e. if our servers handle the emails for it, not a third-party supplier. This option offers you the top degree of safety, but it is not applicable in case only your site is on our servers while the email addresses for the domain name are taken care of in a different place. In either case, the SPF protection service will keep your email addresses risk-free from being used for spam and scam purposes.
