Sender Policy Framework, or SPF, is a validation system, which is designed to stop the so-called email spoofing where an email message can be sent from one address, but to seem as being sent from another, generally with the idea to fraud the recipient in some way. When SPF protection is enabled for a domain name, a specific record is made for it in the Domain Name System and all the DNS servers worldwide get it. The record contains all the email servers that are allowed to send authentic messages from an email address part of the domain. When an e-mail is sent, the very first DNS server it goes to verifies the SPF record and if the sending server is permitted, the message is sent to the target receiver. When, however, the sending server is not present in the SPF record for the given domain, the e-mail message will not be forwarded and it will be discarded. When you use this solution, it'll stop third parties from sending spam messages that seem to have been sent from you.

SPF Protection in Cloud Website Hosting

You'll be able to activate the SPF protection service for your domains with a couple of clicks inside the Hepsia Control Panel, which is included with all our Linux cloud website hosting. This carried out through the section bearing the same name and you can allow the protection for each and every domain name hosted on our modern cloud hosting platform. Using a very handy interface, all you have to type in is the hostname of the mail server that will be permitted to send out messages from your e-mails and its IPv4 or IPv6 address. Of course, you can add several servers too, when needed. If your emails are handled on our end, you can also employ an even more secure option by placing a limit that e-mail messages can be sent only when your domains include our MX records. This option can't be applied when your site is hosted here, but your emails are with a third-party service provider. In either case, the SPF protection option will significantly increase your web safety and prevent other people from counterfeiting your email addresses.

SPF Protection in Semi-dedicated Servers

When you have a semi-dedicated server account with us, you can secure your emails by enabling the SPF security service for any domain hosted in the account with just a few clicks. This can be done through the Emails section of the Hepsia Control Panel which is included with the semi-dedicated accounts and even if you have no previous practical experience with these matters, you won't have any trouble to activate the protection. Everything that you'll need to do will be to choose a domain name from a drop-down menu and then type in the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your e-mail addresses will be mailed around the world only if they were sent from that server. In case your email addresses are handled by our company and not by a third-party provider, you can also use an option for email messages to be mailed only when the domain features our MX records and this would be the safest option.
