Sender Policy Framework, or SPF, is a validation system, which is used 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, often with the idea to scam the recipient in some way. When SPF protection is activated for a domain name, a unique record is generated for it in the Domain Name System and all DNS servers worldwide have it. The record features all of the email servers that are permitted to send authentic messages from an address part of the domain. When an e-mail is sent, the very first DNS server it encounters checks the SPF record and in case the sending server is authorized, the message is sent to the target destination. In case, however, the sending server is not included in the SPF record for the particular domain, the message will not be submitted and it will be discarded. When you employ this service, it will stop third parties from sending spam e-mails which appear to have been sent by you.

SPF Protection in Web Hosting

When you host your domains in a web hosting account with us and we handle the e-mails for them, you will be able to activate SPF protection for them with a couple of clicks inside your Hepsia Control Panel. This service is available in its own section where you're able to see which domain names are already protected. For the ones which aren't, you can activate the SPF protection option and configure a lot of things during this process - the hostnames of the mail servers that are allowed to send messages from your emails, the IPv4 and IPv6 addresses of these servers, as well as to create a rule that emails can be sent only if your domains have our MX records. The last option is the most secure one, and you can use it in the event that we take care of the emails for your domains and you are not using another e-mail provider. The newly created records will be activated within a day and nobody will be able to fake the FROM field in an email using your e-mail addresses.
