Sender Policy Framework, or SPF, is a validation system, which is employed to stop the so-called e-mail spoofing where an e-mail message is sent from one email address, but to look as being sent from a different one, frequently with the objective to fraud the recipient someway. When SPF protection is enabled for a domain, a special record is made for it in the Domain Name System and all of the DNS servers around the world get it. The record features all mail servers that are allowed to send legitimate messages from an e-mail address under the domain. When a message is sent, the very first DNS server it encounters verifies the SPF record and when its sending server is authorized, the message is sent to the target receiver. If, however, the sending server is not included in the SPF record for the given domain, the e-mail message won't be sent and it will be discarded. In case you use this solution, it'll stop third parties from sending spam which look as if they have been sent from you.
SPF Protection in Cloud Website Hosting
You can enable the SPF protection service for your domain names with only a couple of clicks from the Hepsia Control Panel, which is included in all of our Linux cloud website hosting. This carried out through the section bearing an identical name and you are able to enable the protection for any domain name part of our advanced cloud hosting platform. Using a very time and effort saving interface, all you have to type in is the hostname of the mail server which will be approved to send out messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, you can include several servers too, when needed. If your e-mail addresses are taken care of on our end, you can also employ an even more risk-free option by putting a restriction that e-mails can be sent only if your domains include our MX records. This option can't be applied when your site is here, and the email addresses are with a third-party supplier. In either case, the SPF protection option can significantly increase your web protection and prevent other people from counterfeiting your e-mail addresses.
