Sender Policy Framework, or SPF, is a validation system, that is used to prevent the so-called email spoofing where an email message is sent from one e-mail, but to appear as being sent from another one, often with the objective to fraud the recipient someway. If SPF protection is activated for a domain, an exclusive record is made for it in the Domain Name System and all the DNS servers globally receive it. The record includes all of the mail servers that are allowed to send legitimate messages from an email address part of the domain. When an email is sent, the first DNS server it goes to verifies the SPF record and in case its sending server is authorized, the message is sent to the target destination. When, however, the sending server is not present in the SPF record for the given domain, the email message won't be sent and it will be discarded. When you use this service, it'll stop third parties from sending spam messages that appear to have been sent by you.
SPF Protection in Shared Hosting
SPF protection can be enabled for every domain hosted in a shared hosting account on our cloud platform with just a couple of clicks. The function is available in the Emails section of our innovative Hepsia Control Panel and all you need to activate it is to choose one of your domain names from the drop-down list and type in the hostnames along with the IPv4 or IPv6 addresses of the e-mail servers which will be approved to send emails from your emails. As an additional option you may also restrict the e-mails to be sent from your domain only if it has our MX records, i.e. when our servers handle the email addresses for it, not a third-party supplier. This feature provides you with the best level of protection, but it is not applicable when only your website is on our servers while the emails for the domain name are handled in another place. In either case, our SPF protection service will keep your email addresses protected from being used for spam or scam purposes.
SPF Protection in Semi-dedicated Servers
When you host your domain names in a semi-dedicated server account from us, you'll be able to take advantage of the SPF protection feature as a part of the standard collection of services that you will get with this type of hosting. Activating the protection requires just a few simple steps within the Hepsia Control Panel, so that even in case you've never employed such a function before, you won't have any type of troubles. Through an exceptionally easy-to-use interface, you will simply have to insert the details of the mail server that will be authorized to send messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the newly created record propagates, no one will be able to fake any e-mail for that particular domain name and send emails from a server other than the one you've typed in. This does not specifically have to be our mail server, however when we manage your email messages, you'll be able to activate an extra level of security by picking an option that emails can be send out from addresses @your-domain.com only if the domain uses our MX records. Our technical support team will be able to help you 24/7 if you have any kind of questions related to this service.
