Sender Policy Framework, or SPF, is a validation system, which is used to prevent the so-called email spoofing where an email message is sent from one e-mail address, but to look as being sent from another, usually with the idea to fraud the recipient someway. When SPF protection is activated for a domain name, an exclusive record is created for it in the Domain Name System and all of the DNS servers globally get it. The record contains all the email servers that are allowed to send valid messages from an address under the domain. When a message is sent, the very first DNS server it encounters checks the SPF record and in case the sending server is permitted, the message is forwarded to the target destination. When, however, the sending server is not included in the SPF record for the particular domain, the e-mail message will not be forwarded and it will be discarded. In case you use this service, it'll stop third parties from sending spam e-mails which seem to have been sent by you.

SPF Protection in Web Hosting

You can enable the SPF protection service for your domains with only a couple of clicks in the Hepsia Control Panel, which is provided with all of our web hosting plans. This is performed from the section with the very same name and you're able to enable the protection for any domain on our cutting-edge cloud platform. Using a really user-friendly interface, all you will need to submit 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're able to add several servers too, if needed. When your email addresses are managed on our end, you can also take advantage of an even more secure option by setting a restriction that email messages can be sent only if your domain names include our MX records. This alternative can't be used when your web site is hosted with us, but the e-mail addresses are with a third-party provider. Either way, the SPF protection solution can significantly increase your web security and prevent others from spoofing your e-mail addresses.
