SPF, which means Sender Policy Framework, is an e-mail security system, that is designed to confirm if an email message was sent by a certified server. Using SPF protection for a given domain will prevent the forging of emails created with the domain. In simple words: activating this feature for a domain name generates a special record in the Domain Name System (DNS) which includes the IP addresses of the servers which are allowed to send emails from mail boxes under the domain. The moment this record propagates worldwide, it exists on all the DNS servers that direct the Internet traffic. Whenever some e-mail message is sent, the initial DNS server it uses tests if it originates from an accredited server. In the event it does, it is forwarded to the destination address, however if it does not originate from a server indexed in the SPF record for the domain, it's discarded. Thus nobody can mask an e-mail address to make it appear as if you are sending spam. This technique is also called email spoofing.
SPF Protection in Cloud Hosting
When you host your domains in a cloud hosting account on our end and we manage the emails for them, you are able to activate SPF protection for all of them with a few clicks inside your Hepsia Control Panel. This service is available in a separate section where you can view which domain names are already secured. For those that aren't, you'll be able to enable the SPF protection solution and configure numerous things during this process - the hostnames of the mail servers that are allowed to send messages from your mailboxes, the IPv4 and IPv6 addresses of the servers, as well as to create a rule that messages can be sent only when your domains have our MX records. The last choice is the most secure one, and it can be used when we handle the email addresses for your domain names and you are not using a different email provider. The new records will be activated within 24 hours and nobody will be able to fake the FROM field in a message using 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 conventional collection of services that you'll receive using this kind of web hosting. Enabling the protection requires just several simple steps within the Hepsia Control Panel, so that even in case you have never employed this kind of function before, you won't have any troubles. Using an exceptionally easy-to-use interface, you will just need to enter the information of the mail server which will be authorized to send out messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the recently made record propagates, nobody will be able to fake any email address for that particular domain and send e-mails from a server other than the one you've entered. This doesn't specifically have to be our mail server, however if we manage your email messages, you are able to allow an additional level of protection by choosing an option that e-mails can be send out from addresses @your-domain.com only in case the domain uses our MX records. Our technical support staff can assist you 24/7 if you have any kind of questions related to this service.
