Sender Policy Framework, or SPF, is a verification system, that is designed to stop the so-called email spoofing where an e-mail message can be sent from one email, but to seem as being sent from another, typically with the purpose to scam the recipient in some way. When SPF protection is enabled for a domain, an exclusive record is made for it in the Domain Name System and all DNS servers worldwide get it. The record features all of the e-mail servers that are permitted to send legitimate messages from an address within the domain. When an e-mail is sent, the first DNS server it goes to checks the SPF record and in case the sending server is permitted, the message is sent to the targeted receiver. If, however, the sending server is not present in the SPF record for the given domain, the message won't be forwarded and it will be discarded. In the event that you employ this service, it'll prevent third parties from sending spam emails which seem to have been sent from you.

SPF Protection in Hosting

When you host your domain names in a hosting account with us and we manage the e-mail addresses for them, you will be able to activate SPF protection for them with a few clicks inside your Hepsia Control Panel. The service is accessible in its own section where you'll be able to view which domain names are currently protected. For those which aren't, you will be able to enable the SPF protection solution and set up various things during the process - the hostnames of the mail servers that are allowed to send messages from your addresses, the IPv4 and IPv6 addresses of these servers, as well as to set a rule that emails can be sent only when your domains have our MX records. The aforementioned choice is the most secure one, but it can be used in the event that we take care of the email addresses for your domains and do not use some other e-mail supplier. The newly created records will be activated within 24 hours and nobody will be able to forge the FROM field in an email by using your addresses.
