Sender Policy Framework, or SPF, is a verification system, that is employed to prevent the so-called email spoofing where an e-mail message can be sent from one email address, but to look as being sent from a different, frequently with the purpose to fraud the recipient for some reason. If SPF protection is enabled for a domain name, a specific record is created for it in the Domain Name System and all the DNS servers globally receive it. The record contains all of the email servers that are permitted to send valid messages from an email address part of the domain. When an email 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 particular domain, the message won't be forwarded and it'll be discarded. If you use this service, it will stop third parties from sending spam that seem to have been sent from you.
SPF Protection in Cloud Website Hosting
You can enable the SPF protection option for your domains with only a few clicks in the Hepsia Control Panel, which is included with all of our cloud website hosting plans. This carried out via the section with the very same name and you'll be able to enable the protection for each domain name on our exceptional cloud hosting platform. Using a very time and effort saving interface, all you need to type in is the hostname of the mail server that will be approved to send messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you'll be able to include several servers too, when needed. In case your emails are taken care of on our end, you can also use a more risk-free option by putting a limit that e-mail messages can be sent only if your domains feature our MX records. This option can't be applied when your website is here, but your e-mails are with a third-party supplier. Either way, the SPF protection option can definitely increase your web security and stop other people from counterfeiting your e-mail addresses.
