Sender Policy Framework, or SPF, is a validation system, which is designed to stop the so-called e-mail spoofing where an email message is sent from one email address, but to seem as being sent from a different, frequently with the purpose to scam the recipient in some way. If SPF protection is enabled for a domain, a special record is generated for it in the Domain Name System and all the DNS servers around the world receive it. The record includes all e-mail servers that are permitted to send valid messages from an address within the domain. When a message is sent, the first DNS server it encounters checks the SPF record and if the sending server is permitted, the message is sent to the targeted destination. In case, however, the sending server doesn't exist in the SPF record for the specified domain, the email message will not be submitted and it will be discarded. Whenever you employ this service, it will prevent third parties from sending spam which look as if they have been sent from you.

SPF Protection in Shared Website Hosting

If you host your domain names in a shared website hosting account on our end and we handle the emails for them, you'll be able to enable SPF protection for any of them with a couple of clicks in your Hepsia Control Panel. The service is accessible in a section of its own where you can view which domains are currently protected. For those which aren't, you can enable the SPF protection solution and set up a number of things at the same time - the hostnames of the mail servers that are permitted to send messages from your email addresses, the IPv4 and IPv6 addresses of these servers, as well as to set a rule that messages can be sent only when your domains have our MX records. The last mentioned option is the most secure one, but you can use it when we handle the e-mails for your domains and do not use a different e-mail service provider. The new records will be activated within one day and nobody will be able to forge the FROM field in an e-mail by using your e-mail addresses.
