Sender Policy Framework, or SPF, is a validation system, which is employed to stop the so-called e-mail spoofing where an e-mail message is sent from one e-mail, but to seem as being sent from a different, often with the objective to fraud the recipient in some way. When SPF protection is activated for a domain, a specific record is made for it in the Domain Name System and all the DNS servers around the world receive it. The record includes all the email servers that are allowed to send valid messages from an email address part of the domain. When an email is sent, the very first DNS server it encounters checks the SPF record and when the sending server is authorized, the message is forwarded to the targeted destination. If, however, the sending server is not contained in the SPF record for the specified domain, the email message will not be forwarded and it will be discarded. In case you employ this service, it'll stop third parties from sending spam messages which appear to have been sent from you.

SPF Protection in Cloud Website Hosting

If you host your domain names in a cloud website hosting account on our end and we handle the e-mails for them, you are able to enable SPF protection for any of them with several clicks inside your Hepsia Control Panel. This service can be found in a section of its own where you will be able to see which domain names are already secured. For the ones that aren't, you will be able to activate the SPF protection service and configure numerous things during this process - the hostnames of the mail servers that are permitted to send messages from your emails, the IPv4 and IPv6 addresses of the servers, as well as 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, but you can use it when we manage the emails for your domain names and you are not using a different e-mail supplier. The newly created records will be activated within 24 hours and nobody will be able to forge the FROM field in a message using your addresses.

SPF Protection in Semi-dedicated Servers

If you have a semi-dedicated server account from us, you'll be able to protect your email addresses by activating the SPF protection service for every domain in the account with only a couple of clicks. This is done from the Emails section of our Hepsia Control Panel which is provided with the semi-dedicated accounts and even in case you have no previous practical experience with these things, you will not have any kind of trouble to activate the protection. All that you'll need to do will be to pick a domain from a drop-down list then type in the mail server hostname and IPv4 or IPv6 address. The moment the updated record propagates, messages from your e-mail addresses will be delivered globally only if they were sent from that server. In case your emails are managed by our company and not by some third-party provider, you can also benefit from an option for emails to be mailed only if the domain name contains our MX records and this is the safest option.
