Sender Policy Framework, or SPF, is a validation system, which is designed to prevent the so-called email spoofing where an email message is sent from one email address, but to appear as being sent from a different one, typically with the idea to fraud the recipient someway. If SPF protection is enabled for a domain name, a special record is generated for it in the Domain Name System and all DNS servers worldwide have it. The record contains all email servers that are permitted to send authentic messages from an email address part of the domain. When an e-mail is sent, the first DNS server it goes to checks the SPF record and in case its sending server is authorized, the message is forwarded to the targeted receiver. In case, however, the sending server is not included in the SPF record for the given domain, the message will not be submitted and it will be removed. Whenever you employ this solution, it'll stop third parties from sending spam that appear to have been sent by you.
SPF Protection in Shared Hosting
You're able to enable the SPF protection service for your domains with just a few clicks inside the Hepsia Control Panel, which comes with all of our Linux shared hosting plans. This carried out through the section bearing an identical name and you'll be able to set up the protection for each and every domain on our cutting-edge cloud platform. Using a very simple interface, all you have to type in is the hostname of the mail server which will be approved to send out messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you'll be able to include several servers as well, when needed. If your email addresses are managed by us, you can also take advantage of an even more secure option by placing a restriction that emails can be sent only if your domain names include our MX records. This solution can't be used in case your web site is hosted with us, and the e-mail addresses are with some third-party provider. Either way, the SPF protection option will vastly enhance your web security and stop others from spoofing your email addresses.

Once the recently made record propagates, no one will be able to fake any e-mail address for that particular domain and send out e-mail messages from a server different from the one you have typed in.
