Sender Policy Framework, or SPF, is a validation system, that is used to stop the so-called email spoofing where an e-mail message can be sent from one email address, but to look as being sent from a different one, usually with the objective to fraud the recipient for some reason. If SPF protection is activated for a domain, a unique record is made for it in the Domain Name System and all DNS servers worldwide get it. The record features all of the email servers that are permitted to send valid messages from an email address within the domain. When an e-mail is sent, the very first DNS server it encounters checks the SPF record and in case its sending server is authorized, the message is forwarded to the targeted destination. When, however, the sending server is not contained in the SPF record for the specified domain, the email message won't be forwarded and it will be discarded. In case you employ this solution, it will stop third parties from sending spam messages which appear to have been sent from you.

SPF Protection in Cloud Web Hosting

SPF protection can be enabled for each domain name hosted in a cloud web hosting account on our cloud platform with just a couple of clicks. The option can be found in the Emails section of our exceptional Hepsia Control Panel and what is needed to activate it is to pick one of your domains 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 authorized to send emails from your emails. As an added option you can even restrict the email messages to be sent from your domain only if it has our MX records, i.e. when our servers manage the email addresses for it, not some third-party supplier. This solution will give you the highest degree of security, but it's not applicable when only your site is on our servers while your emails for the domain name are handled in a different place. In either case, the SPF protection service will keep your email addresses secure from being used for spam and/or scam purposes.

SPF Protection in Semi-dedicated Servers

When you host your domain names in a semi-dedicated server account from us, you are able to employ the SPF protection feature as a part of the regular collection of services that you will have using this kind of web hosting. Starting the protection involves only a few simple steps within the Hepsia Control Panel, therefore even if you've never used this type of feature before, you won't have any type of troubles. Through a very easy to work with interface, you will just have to insert the information of the mail server that will be authorized to send messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the newly generated record propagates, no one will be able to fake any e-mail address for that particular domain and send e-mails from a server other than the one you have entered. This does not necessarily have to be our mail server, but in case we handle your e-mails, you're 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 crew will be able to assist you 24/7 if you have any kind of questions related to this service.
