Sender Policy Framework, or SPF, is a verification system, that is employed to stop the so-called e-mail spoofing where an email message can be sent from one email, but to seem as being sent from a different one, usually with the objective to fraud the recipient in some way. If SPF protection is enabled for a domain name, a unique record is made for it in the Domain Name System and all the DNS servers around the world receive it. The record contains all e-mail servers that are permitted to send valid messages from an address part of the domain. When an e-mail is sent, the first DNS server it goes to checks the SPF record and in case its sending server is permitted, the message is sent to the target receiver. In case, however, the sending server is not included in the SPF record for the given domain, the email message won't be forwarded and it will be discarded. In the event that you use this solution, it will prevent third parties from sending spam messages that seem to have been sent by you.
SPF Protection in Cloud Hosting
You are able to enable the SPF protection option for your domains with a few clicks in the Hepsia Control Panel, which is provided with all of our cloud plans. This is performed through the section bearing the very same name and you're able to set up the protection for any domain name hosted on our outstanding cloud hosting platform. Using a very intuitive interface, all you need to submit is the hostname of the mail server that will be accredited to send messages from your email addresses and its IPv4 or IPv6 address. Of course, you're able to include several servers as well, if needed. When your emails are managed by us, you can also employ a more risk-free option by setting a restriction that messages can be sent only if your domain names have our MX records. This solution can't be applied if your website is hosted with us, but your email addresses are with some third-party provider. Either way, the SPF protection solution will definitely increase your online safety and prevent other people from forging your e-mail addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account from our company, you can protect your email addresses by enabling the SPF protection service for any domain in your account with just a couple of clicks.

All that you will have to do will be to choose a domain from a drop-down menu then type in the mail server hostname and IPv4 or IPv6 address. When the new record propagates, messages from your e-mail addresses will be mailed around the world only if they're sent from that particular server. In case your email addresses are taken care of by our company and not by some third-party supplier, you'll also be able to take advantage of an option for emails to be mailed only if the domain includes our MX records and the aforementioned is the safest option.
