Sender Policy Framework, or SPF, is a validation system, that is employed to prevent the so-called email spoofing where an email message is sent from one address, but to appear as being sent from a different one, ordinarily with the purpose to fraud the recipient someway. When SPF protection is activated for a domain name, a unique record is created for it in the Domain Name System and all the DNS servers globally have it. The record includes all of the mail servers that are allowed to send valid messages from an email address part of the domain. When a message is sent, the first DNS server it goes to checks the SPF record and in case its sending server is authorized, the message is forwarded to the target receiver. If, however, the sending server is not present in the SPF record for the given domain, the e-mail message won't be sent and it'll be discarded. In the event that you use this solution, it will stop third parties from sending spam that seem to have been sent by you.
SPF Protection in Shared Web Hosting
If you host your domain names in a shared web hosting account with us and we manage the e-mails for them, you will be able to activate SPF protection for them with several clicks in your Hepsia Control Panel. The service can be found in a separate section where you're able to view which domain names are currently secured. For the ones that are not, you can activate the SPF protection option and manage a variety of things during this process - the hostnames of the mail servers that are permitted to send messages from your mailboxes, the IPv4 and IPv6 addresses of these servers, and to set a rule that emails can be sent only when your domains include our MX records. The last choice is the most secure one, and it can be used when we handle the e-mail addresses for your domains and you are not using another e-mail service provider. The new records will be activated within one day and nobody will be able to forge the FROM field in an email using your email addresses.
SPF Protection in Semi-dedicated Servers
The Hepsia website hosting Control Panel, that is included with all of our semi-dedicated plans, provides you with an incredibly easy-to-use interface to activate the SPF protection service for every domain that you host inside your new account. A couple of clicks in the Emails section of Hepsia will be enough for that and you will only have to type in the hostname and the IP address of the mail server which will be allowed to send out messages from your e-mails. In case the email messages are taken care of by us and not by another provider, you will be able to increase the security level even further and benefit from an option for the outgoing emails to be sent only if your domains feature our MX records. This option gives you increased control and it will eliminate any possibility of anybody faking your email addresses with the intention of spamming and scamming people. It is not applicable if just your site is on our state-of-the-art cloud hosting platform, while your emails are handled by another provider. If you are not sure what options to pick, our tech support team will assist you 24/7.
