Sender Policy Framework, or SPF, is a verification system, that is used to stop the so-called e-mail spoofing where an e-mail message is sent from one email, but to look as being sent from another one, usually with the purpose to fraud the recipient in some way. If SPF protection is activated for a domain name, a special record is created for it in the Domain Name System and all DNS servers globally get it. The record features all the mail servers that are allowed to send legitimate messages from an e-mail address under the domain. When an email is sent, the very first DNS server it encounters checks the SPF record and if its sending server is permitted, the message is sent to the target destination. If, however, the sending server doesn't exist in the SPF record for the particular domain, the message won't be submitted and it will be discarded. In case you employ this service, it'll stop third parties from sending spam e-mails that seem to have been sent by you.

SPF Protection in Hosting

You're able to enable the SPF protection service for your domain names with just a few clicks from the Hepsia Control Panel, which is included with our Linux hosting plans. This is done via the section bearing an identical name and you'll be able to allow the protection for each and every domain name on our modern cloud platform. Using a very user-friendly interface, all you need to enter is the hostname of the mail server which will be accredited to send out messages from your e-mails and its IPv4 or IPv6 address. Of course, you're able to include several servers as well, if needed. When your e-mail addresses are handled by us, you can also take advantage of an even more secure option by setting a restriction that messages can be sent only if your domains include our MX records. This option cannot be used when your site is hosted here, but the email addresses are with some third-party supplier. Either way, the SPF protection solution can strongly improve your online security and stop other people from forging your e-mail addresses.
