Sender Policy Framework, or SPF, is a validation system, that is designed to prevent the so-called e-mail spoofing where an email message can be sent from one email, but to appear as being sent from another, often with the idea to fraud the recipient in some way. If SPF protection is enabled for a domain, a specific record is generated for it in the Domain Name System and all of the DNS servers globally have it. The record features all email servers that are allowed to send authentic messages from an e-mail address part of the domain. When an e-mail is sent, the first DNS server it encounters verifies the SPF record and if the sending server is permitted, the message is forwarded to the targeted receiver. When, however, the sending server is not present in the SPF record for the particular domain, the email message will not be sent and it'll be removed. When you employ this service, it'll stop third parties from sending spam messages which look as if they have been sent from you.
SPF Protection in Cloud Website Hosting
If you host your domains in a cloud website hosting account on our end and we manage the emails for them, you are able to activate SPF protection for them with several clicks in your Hepsia Control Panel. The service is accessible in its own section where you're able to see which domains are already protected. For the ones that aren't, you can activate the SPF protection option and configure numerous things at the same time - the hostnames of the mail servers that are permitted to send messages from your email addresses, the IPv4 and IPv6 addresses of these servers, and even to set a rule that email messages can be sent only if your domains have our MX records. The last solution is the most secure one, and it can be used in the event that we handle the e-mail addresses for your domain names and you're not using some other e-mail service provider. The newly generated records will propagate within 1 day and nobody will be able to fake the FROM field in an e-mail with your addresses.
