Sender Policy Framework, or SPF, is a validation system, that is used to prevent the so-called e-mail spoofing where an e-mail message is sent from one address, but to appear as being sent from another one, ordinarily with the purpose to fraud the recipient someway. If SPF protection is enabled for a domain, a specific record is made for it in the Domain Name System and all of the DNS servers around the world get it. The record contains all the mail servers that are allowed to send legitimate messages from an e-mail address under the domain. When an e-mail is sent, the very first DNS server it encounters verifies the SPF record and in case its sending server is authorized, the message is sent to the target receiver. If, however, the sending server is not contained in the SPF record for the given domain, the e-mail message will not be sent and it'll be discarded. If you use this solution, it'll stop third parties from sending spam e-mails that look as if they have been sent from you.

SPF Protection in Shared Web Hosting

You can enable the SPF protection option for your domains with just a few clicks inside the Hepsia Control Panel, which is provided with our shared web hosting. This is done through the section with the same name and you can allow the protection for each domain name on our exceptional cloud platform. Using a really handy interface, all you'll have to enter is the hostname of the mail server which will be approved to send out messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, it is possible to add several servers as well, when needed. In case your e-mails are taken care of by us, you can also use a more secure option by placing a restriction that e-mails can be sent only if your domain names feature our MX records. This solution cannot be used in case your site is here, while your e-mails are with a third-party service provider. In either case, the SPF protection solution will tremendously enhance your online safety and prevent other people from spoofing your e-mail addresses.
