SPF, which is an abbreviation for Sender Policy Framework, is a validation system that is aimed at preventing the so-called email faking. Essentially, this means sending some message from one e-mail and making it seem to be sent from another with the idea to scam in some manner the person getting it. When the SPF protection is active for a domain name, a record which has all mail servers authorized to email messages with addresses within the domain is generated. The record is kept on all of the DNS servers that route the web traffic internationally, thus they all can identify if an e-mail message originates from a valid server or not. The verification is done at the first server where the email goes through and in the first case the message is forwarded, but in the second it's removed and it never reaches the supposed recipient. Using SPF records for your domains will stop any unwanted people from using your emails for malicious purposes.
SPF Protection in Cloud Website Hosting
When you host your domains in a cloud website hosting account with us and we handle the e-mails for them, you will be able to activate SPF protection for any of them with several clicks inside your Hepsia Control Panel. The service is available in a section of its own where you can view which domains are currently protected. For those that aren't, you can enable the SPF protection service and manage a number of things in the process - the hostnames of the mail servers that are permitted to send messages from your mailboxes, the IPv4 and IPv6 addresses of these servers, as well as to create a rule that emails can be sent only if your domains include our MX records. The last mentioned choice is the most secure one, but it can be used if we take care of the e-mail addresses for your domains and you are not using another e-mail supplier. The new records will propagate within a day and nobody will be able to forge the FROM field in an e-mail using your e-mail addresses.
