Sender Policy Framework, or SPF, is a verification system, which is intended to stop the so-called e-mail spoofing where an e-mail message can be sent from one e-mail address, but to seem as being sent from another one, ordinarily with the idea to fraud the recipient in some way. If SPF protection is activated for a domain name, a specific record is created for it in the Domain Name System and all the DNS servers around the world receive it. The record contains all of the mail servers that are permitted to send authentic messages from an e-mail address part of the domain. When a message is sent, the first DNS server it goes to checks the SPF record and in case its sending server is permitted, the message is forwarded to the targeted receiver. In case, however, the sending server is not contained in the SPF record for the given domain, the email message will not be forwarded and it will be discarded. If you use this service, it'll prevent third parties from sending spam messages which look as if they have been sent by you.

SPF Protection in Shared Web Hosting

If you host your domain names in a shared web hosting account on our end and we handle the e-mail addresses for them, you are able to enable SPF protection for any of them with a few clicks inside your Hepsia Control Panel. The service is available in its own section where you are able to see which domains are currently secured. For the ones which aren't, you will be able to enable the SPF protection solution and manage a lot of things in the process - the hostnames of the mail servers that are permitted to send messages from your emails, the IPv4 and IPv6 addresses of the servers, and even to set a rule that messages can be sent only when your domains include our MX records. The last solution is the most secure one, and you can use it when we manage the email addresses for your domain names and you're not using some other e-mail provider. The newly created records will be activated within a day and nobody will be able to forge the FROM field in an e-mail with your email addresses.
