Sender Policy Framework, or SPF, is a verification system, which is employed to prevent the so-called e-mail spoofing where an e-mail message is sent from one email address, but to appear as being sent from a different one, generally with the purpose to scam the recipient for some reason. If SPF protection is enabled for a domain, a unique record is generated for it in the Domain Name System and all of the DNS servers worldwide receive it. The record contains all of the email servers that are allowed to send valid messages from an address part of the domain. When a message is sent, the first DNS server it encounters checks the SPF record and if the sending server is permitted, the message is forwarded to the targeted receiver. If, however, the sending server is not contained in the SPF record for the given domain, the email message will not be submitted and it will be discarded. When you use this service, it will stop third parties from sending spam that seem to have been sent from you.
SPF Protection in Shared Web Hosting
You'll be able to enable the SPF protection option for your domain names with only a couple of clicks inside the Hepsia Control Panel, which is provided with our Linux shared web hosting. This is performed through the section with the same name and you'll be able to enable the protection for each and every domain name on our outstanding cloud hosting platform. Using a really convenient interface, all you will need to submit is the hostname of the mail server which will be permitted to send messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, it is possible to include several servers as well, if needed. In case your e-mail addresses are handled by us, you can also use a more secure option by placing a restriction that email messages can be sent only if your domain names have our MX records. This alternative can't be used in case your site is hosted with us, while the emails are with some third-party provider. In either case, the SPF protection option will really increase your online safety and prevent others from spoofing your email addresses.
SPF Protection in Semi-dedicated Servers
If you host your domain names in a semi-dedicated server account from us, you'll be able to employ the SPF protection feature as a part of the regular collection of services that you will have using this type of hosting. Starting the protection involves only several simple steps within the Hepsia Control Panel, thus even if you haven't used such a function before, you will not have any issues. Through a really user-friendly interface, you will only need to enter the info of the mail server which will be certified to send messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the newly made record propagates, nobody will be able to forge any e-mail address for that particular domain name and send out messages from a server other than the one you have typed in. This doesn't specifically have to be our mail server, still if we handle your e-mails, you will be able to activate an extra level of protection by picking an option that email messages can be send out from addresses @your-domain.com only in the event that the domain employs our MX records. Our tech support team can help you 24/7 in case you have any questions related to this service.
