Sender Policy Framework, or SPF, is a verification system, which is designed to stop the so-called e-mail spoofing where an email message is sent from one address, but to look as being sent from a different, usually with the objective to scam the recipient in some way. When SPF protection is enabled for a domain name, a unique record is generated for it in the Domain Name System and all DNS servers worldwide get it. The record contains all the email servers that are permitted to send authentic messages from an e-mail address part of 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 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 will not be sent and it will be removed. Whenever you use this service, it will stop third parties from sending spam messages which look as if they have been sent by you.

You can activate the SPF protection service for your domain names with a few clicks inside the Hepsia Control Panel, which comes with all of our shared plans. This carried out via the section with an identical name and you are able to set up the protection for any domain hosted on our innovative cloud hosting platform. Using a really simple interface, all you will need to type in is the hostname of the mail server that will be approved to send out messages from your e-mails and its IPv4 or IPv6 address. Of course, you can include several servers as well, when needed. In case your e-mail addresses are taken care of by us, you can also use a more risk-free option by placing a restriction that email messages can be sent only if your domains include our MX records. This option can't be used when your website is hosted here, and your emails are with a third-party supplier. Either way, the SPF protection option will significantly improve your online safety and prevent other people from counterfeiting your email addresses.
