Sender Policy Framework, or SPF, is a verification system, which is used to prevent the so-called e-mail spoofing where an e-mail message can be sent from one email address, but to appear as being sent from a different, typically with the purpose to scam the recipient in some way. If SPF protection is activated for a domain name, a specific record is made for it in the Domain Name System and all of the DNS servers globally get it. The record features all of the email servers that are permitted to send valid messages from an email address under the domain. When an e-mail is sent, the very first DNS server it goes to verifies the SPF record and if the sending server is authorized, the message is forwarded to the targeted destination. In case, however, the sending server is not present in the SPF record for the given domain, the e-mail message won't be submitted and it will be discarded. In case you use this service, it'll prevent third parties from sending spam emails that appear to have been sent by you.
SPF Protection in Shared Web Hosting
SPF protection can be enabled for each domain name hosted in a shared web hosting account on our cloud hosting platform with no more than a couple of clicks. The function is accessible in the Emails section of our cutting-edge Hepsia Control Panel and all it takes to enable it is to choose one of your domain names from the drop-down menu and type in the hostnames as well as the IPv4 or IPv6 addresses of the mail servers which will be authorized to send emails from your email addresses. As an added option you can also restrict the messages to be sent from your domain only if it includes our MX records, i.e. when our servers manage the email addresses for it, not some third-party supplier. This solution gives you the top degree of safety, but it's not applicable if only your site is on our servers while your e-mail addresses for the domain name are managed elsewhere. Regardless, the SPF protection service will keep your email addresses safe from being used for spam and/or scam purposes.
