SPF, which stands for Sender Policy Framework, is an e-mail security system, which is used to verify whether an email message was sent by a certified server. Using SPF protection for a particular domain will stop the forging of emails generated with the domain. In simple words: activating this function for a domain creates a special record in the Domain Name System (DNS) which contains the IP addresses of the servers that are permitted to send email messages from mailboxes under the domain. As soon as this record propagates worldwide, it will exist on all DNS servers that route the Internet traffic. Every time some email message is sent, the initial DNS server it uses checks if it originates from an authorized server. When it does, it is sent to the destination address, however if it doesn't come from a server listed in the SPF record for the domain, it's rejected. Thus nobody will mask an email address and make it look as if you're distributing spam. This approach is also known as email spoofing.
SPF Protection in Shared Hosting
You'll be able to enable the SPF protection service for your domains with only a few clicks inside the Hepsia Control Panel, which is included in our Linux shared hosting. This is done via the section with the same name and you'll be able to set up the protection for each domain hosted on our outstanding cloud hosting platform. Using a very handy interface, all you will need to submit is the hostname of the mail server which will be approved to send out messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, you can include several servers as well, if needed. In case your e-mails are managed on our end, you can also use a more secure option by setting a restriction that email messages can be sent only if your domain names include our MX records. This alternative cannot be used if your site is here, while the emails are with some third-party service provider. Either way, the SPF protection solution will really enhance your web security and prevent other people from forging your email addresses.
SPF Protection in Semi-dedicated Hosting
When you host your domains in a semi-dedicated server account from our company, you are able to use the SPF protection feature as a part of the standard set of services that you'll get using this type of hosting. Enabling the protection will require just a couple of easy steps in the Hepsia Control Panel, thus even in case you've never employed this kind of function before, you won't have any type of troubles. Using a very easy to work with interface, you will simply need to insert the details of the mail server which will be certified to send out messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the recently made record propagates, nobody will be able to forge any email for that particular domain name and send out messages from a server other than the one you have typed in. This doesn't necessarily have to be our mail server, yet when we take care of your e-mails, you'll be able to allow an additional level of protection by picking an option that e-mail messages can be send from addresses @your-domain.com only in case the domain uses our MX records. Our tech support crew will be able to assist you 24/7 in case you have any questions related to this service.
