Sender Policy Framework, or SPF, is a verification system, which is employed to stop the so-called e-mail spoofing where an e-mail message is sent from one e-mail, but to appear as being sent from a different one, usually with the idea to scam the recipient someway. If SPF protection is activated for a domain, an exclusive record is created for it in the Domain Name System and all the DNS servers around the world have it. The record includes all the e-mail servers that are allowed to send legitimate messages from an e-mail address within the domain. When an e-mail is sent, the very first DNS server it goes to checks the SPF record and if its sending server is permitted, the message is forwarded to the targeted receiver. If, however, the sending server is not present in the SPF record for the specified domain, the e-mail message won't be submitted and it will be discarded. In the event that you employ this service, it will stop third parties from sending spam e-mails that look as if they have been sent by you.
SPF Protection in Shared Web Hosting
SPF protection can be enabled for every domain hosted in a shared web hosting account on our cloud platform with no more than a few clicks. The option is available in the Emails section of our leading-edge Hepsia Control Panel and what is needed to enable it is to pick one of your domain names from the drop-down list and then enter the hostnames as well as the IPv4 or IPv6 addresses of the email servers which will be permitted to send messages from your emails. As an additional option you may also restrict the messages to be sent from your domain only if it includes our MX records, i.e. if our servers handle the e-mail addresses for it, not a third-party provider. This option provides you with the best degree of protection, but it is not applicable if only your web site is on our servers while the email addresses for the domain are handled elsewhere. In either case, our SPF protection service will keep your email addresses safe from being used for spam and/or scam purposes.
SPF Protection in Semi-dedicated Servers
If you host your domain names in a semi-dedicated server account with us, you can take advantage of the SPF protection feature as a part of the regular set of services that you will receive with this type of hosting. Starting the protection involves only several easy steps in the Hepsia Control Panel, so even when you haven't used this kind of function before, you won't have any kind of issues. Employing a very intuitive interface, you'll just need to enter the details of the mail server which will be permitted to send messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the newly made record propagates, nobody will be able to fake any email for that particular domain and send e-mail messages from a server other than the one you've entered. This doesn't necessarily have to be our mail server, still if we handle your emails, you're able to enable an extra level of protection by picking an option that emails can be send out from addresses @your-domain.com only in the event that the domain employs our MX records. Our tech support crew can help you 24/7 in case you have any kind of questions related to this service.
