Sender Policy Framework, or SPF, is a verification system, that is intended to stop the so-called email spoofing where an email message can be sent from one e-mail address, but to look as being sent from another one, frequently with the idea to scam the recipient in some way. When SPF protection is activated for a domain, a unique record is made for it in the Domain Name System and all DNS servers around the world have it. The record includes all the mail servers that are permitted to send valid 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 in case its sending server is permitted, the message is sent to the target destination. In case, however, the sending server is not present in the SPF record for the specified domain, the e-mail message won't be sent and it'll be discarded. When you use this solution, it'll prevent third parties from sending spam messages that look as if they have been sent from you.
SPF Protection in Website Hosting
You are able to activate the SPF protection option for your domains with just a couple of clicks inside the Hepsia Control Panel, which comes with all of our Linux website hosting. This carried out from the section with the very same name and you are able to allow the protection for any domain hosted on our modern cloud hosting platform. Using a very time and effort saving interface, all you'll have to enter is the hostname of the mail server which will be authorized to send out messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you can include several servers as well, when needed. When your emails are managed by us, you can also take advantage of an even more secure option by setting a restriction that e-mails can be sent only if your domains include our MX records. This alternative can't be used when your website is here, but your e-mails are with some third-party supplier. In either case, the SPF protection solution will considerably enhance your web security and prevent others from spoofing your email addresses.
