Sender Policy Framework, or SPF, is a verification system, that is employed to stop the so-called email spoofing where an e-mail message can be sent from one e-mail address, but to appear as being sent from another one, typically with the objective to scam the recipient in some way. When SPF protection is enabled for a domain, an exclusive record is generated for it in the Domain Name System and all DNS servers worldwide receive it. The record contains all email servers that are allowed to send valid messages from an email address part of the domain. When an email is sent, the first DNS server it encounters checks the SPF record and when the sending server is authorized, the message is sent to the targeted destination. If, however, the sending server is not contained in the SPF record for the particular domain, the e-mail message will not be submitted and it will be removed. When 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 Web Hosting
If you host your domains in a cloud web hosting account with us and we manage the emails for them, you are able to enable SPF protection for any of them with several clicks in your Hepsia Control Panel. The service is accessible in a separate section where you'll be able to view which domains are already protected. For the ones which aren't, you'll be able to activate the SPF protection service and set up numerous things in 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 create a rule that email messages can be sent only when your domain names include our MX records. The last solution is the most secure one, but you can use it if we take care of the email addresses for your domain names and you are not using some other e-mail service provider. The new records will propagate within 24 hours and nobody will be able to fake the FROM field in a message using your addresses.
