SPF, which means Sender Policy Framework, is an email safety system, that is employed to verify if an email message was sent by an official server. Using SPF protection for a particular domain will prevent the forging of email addresses generated with the domain. In simple words: enabling this attribute for a domain creates a special record in the Domain Name System (DNS) which contains the IP addresses of the servers that are permitted to send email messages from mail boxes under the domain. As soon as this record propagates worldwide, it exists on all of the DNS servers that direct the Internet traffic. Any time some email message is sent, the initial DNS server it goes through checks whether it comes from an official server. If it does, it is forwarded to the destination address, yet when it doesn't come from a server listed in the SPF record for the domain, it is discarded. Thus nobody will be able to mask an e-mail address and make it appear as if you're distributing spam. This technique is also known as email spoofing.
SPF Protection in Shared Web Hosting
When you host your domain names in a shared web hosting account with us and we handle the e-mails for them, you will be able to enable SPF protection for all of them with several clicks in your Hepsia Control Panel. This service can be found in a separate section where you'll be able to view which domain names are currently protected. For the ones which aren't, you'll be able to activate the SPF protection option and manage various things at the same time - the hostnames of the mail servers that are allowed to send messages from your addresses, the IPv4 and IPv6 addresses of the servers, as well as to set a rule that emails can be sent only when your domains include our MX records. The last mentioned choice is the most secure one, but it can be used in the event that we take care of the emails for your domains and do not use another email provider. The newly created records will propagate within one day and nobody will be able to fake the FROM field in a message with your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
When you host your domain names in a semi-dedicated server account with our company, you are able to take advantage of the SPF protection feature as part of the standard group of services that you'll receive using this kind of website hosting. Starting the protection involves only a couple of easy steps inside the Hepsia Control Panel, so that even in the event that you haven't used this kind of function before, you won't have any type of problems. Through an exceptionally time and effort saving interface, you will only have to insert the info of the mail server that will be permitted to send messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the recently made record propagates, nobody will be able to fake any email address for that particular domain and send out e-mails from a server other than the one you've entered. This does not necessarily have to be our mail server, still if we manage your e-mails, you'll be able to enable one more level of security by picking an option that e-mails can be send from addresses @your-domain.com only if the domain employs our MX records. Our tech support staff will be able to help you 24/7 in case you have any kind of questions related to this service.
