Sender Policy Framework, or SPF, is a validation system, which is employed to stop the so-called email spoofing where an e-mail message is sent from one email address, but to look as being sent from another one, typically with the objective to scam the recipient in some way. When SPF protection is activated for a domain name, an exclusive record is created for it in the Domain Name System and all the DNS servers globally get it. The record features all of the mail servers that are permitted to send legitimate messages from an e-mail address within the domain. When an email is sent, the first DNS server it goes to verifies the SPF record and if the sending server is permitted, the message is forwarded to the target receiver. When, however, the sending server doesn't exist in the SPF record for the given domain, the e-mail message won't be forwarded and it'll be removed. In case you employ this service, it'll prevent third parties from sending spam emails that seem to have been sent by you.
SPF Protection in Shared Web Hosting
You can activate the SPF protection option for your domain names with only a few clicks inside the Hepsia Control Panel, which is provided with all of our Linux shared web hosting packages. This is performed through the section bearing the very same name and you are able to allow the protection for each domain hosted on our cutting-edge cloud hosting platform. Using a really time and effort saving interface, all you will have to submit is the hostname of the mail server which will be approved to send messages from your emails and its IPv4 or IPv6 address. Last, but not least, you're able to add several servers too, when needed. If your e-mails are managed on our end, you may also use an even more risk-free option by placing a restriction that e-mail messages can be sent only if your domain names have our MX records. This alternative can't be applied in case your website is hosted here, but the e-mail addresses are with some third-party service provider. In either case, the SPF protection solution can considerably increase your online safety and prevent other people from forging your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
If you host your domains in a semi-dedicated server account with our company, you are able to use the SPF protection feature as a part of the conventional set of services that you'll receive using this type of web hosting. Activating the protection involves just a couple of simple steps in the Hepsia Control Panel, therefore even when you haven't used this type of feature before, you won't have any issues. Employing a really user-friendly interface, you'll only have to type in the details of the mail server that will be certified to send messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the newly made record propagates, nobody will be able to forge any email address for that particular domain and send e-mails from a server other than the one you have typed in. This doesn't necessarily have to be our mail server, still if we take care of your e-mails, you're able to enable an additional level of protection by picking an option that email messages can be send out from addresses @your-domain.com only if the domain uses our MX records. Our technical support crew will be able to assist you 24/7 if you have any questions about this service.
