Sender Policy Framework, or SPF, is a validation system, which is intended to stop the so-called email spoofing where an email message can be sent from one e-mail address, but to appear as being sent from another one, often with the purpose to scam the recipient someway. If SPF protection is activated for a domain name, an exclusive record is created for it in the Domain Name System and all of the DNS servers around the world receive it. The record includes all e-mail servers that are permitted to send legitimate messages from an email address under the domain. When a message is sent, the first DNS server it goes to verifies the SPF record and in case the sending server is authorized, the message is sent to the targeted destination. If, however, the sending server is not present in the SPF record for the given domain, the email message won't be forwarded and it will be removed. When you employ this solution, it will stop third parties from sending spam messages which look as if they 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'll be able to activate SPF protection for them with a few clicks inside your Hepsia Control Panel. This service is available in a separate section where you can see which domain names are currently protected. For the ones that aren't, you can enable the SPF protection option and configure a lot of things during the process - the hostnames of the mail servers that are allowed to send messages from your e-mails, the IPv4 and IPv6 addresses of these servers, and to create a rule that emails can be sent only if your domain names include our MX records. The last mentioned solution is the most secure one, but it can be used in the event that we handle the e-mails for your domains and do not use a different email provider. The newly created records will be activated within 24 hours and nobody will be able to fake the FROM field in an e-mail by using your e-mail addresses.
