Sender Policy Framework, or SPF, is a validation system, that is intended to prevent the so-called email spoofing where an email message can be sent from one e-mail address, but to appear as being sent from a different one, generally with the objective to scam the recipient someway. If SPF protection is enabled for a domain, a unique record is created for it in the Domain Name System and all of the DNS servers worldwide have it. The record contains all the mail servers that are permitted to send authentic messages from an e-mail address within the domain. When an email is sent, the very first DNS server it encounters checks the SPF record and when the sending server is permitted, the message is sent to the target destination. In case, however, the sending server is not included in the SPF record for the given domain, the message won't be sent and it will be discarded. In the event that you use this service, it will prevent third parties from sending spam that appear to have been sent from you.
SPF Protection in Cloud Website Hosting
You can activate the SPF protection option for your domains with just a few clicks inside the Hepsia Control Panel, which is included with our cloud website hosting services. This carried out through the section bearing the same name and you can set up the protection for each domain hosted on our revolutionary cloud platform. Using a very intuitive interface, all you will need to enter is the hostname of the mail server which will be accredited to send messages from your e-mail addresses and its IPv4 or IPv6 address. Last, but not least, you can add several servers as well, when needed. If your e-mails are taken care of by us, you may also take advantage of a more risk-free option by setting a restriction that e-mail messages can be sent only when your domains include our MX records. This solution cannot be applied in case your website is hosted here, but your emails are with some third-party provider. Either way, the SPF protection option will tremendously increase your web security and stop others from spoofing your email addresses.
