Sender Policy Framework, or SPF, is a verification system, which is designed to prevent the so-called e-mail spoofing where an e-mail message can be sent from one email address, but to appear as being sent from another one, ordinarily with the idea to scam the recipient in some way. If SPF protection is enabled for a domain name, an exclusive record is made for it in the Domain Name System and all DNS servers globally get it. The record includes all email servers that are permitted to send legitimate messages from an address within the domain. When an email is sent, the first DNS server it encounters verifies the SPF record and in case the sending server is permitted, the message is forwarded to the targeted destination. In case, however, the sending server doesn't exist in the SPF record for the specified domain, the message won't be submitted and it'll be discarded. Whenever you use this service, it'll stop third parties from sending spam e-mails which seem to have been sent by you.

SPF Protection in Shared Hosting

If you host your domains in a shared hosting account on our end and we manage the e-mails for them, you'll be able to enable SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. The service is accessible in a separate section where you will be able to view which domains are currently protected. For those that are not, you will be able to enable the SPF protection service and configure a variety of things at the same time - the hostnames of the mail servers that are allowed to send messages from your e-mails, the IPv4 and IPv6 addresses of these servers, as well as to set a rule that email messages can be sent only if your domain names use our MX records. The last mentioned option is the most secure one, but you can use it if we manage the e-mail addresses for your domains and do not use some other email provider. The newly generated records will be activated within a day and nobody will be able to forge the FROM field in an e-mail by using your addresses.

SPF Protection in Semi-dedicated Hosting

The SPF protection function is provided with all Linux semi-dedicated packages, so when you host your domains in an account on our cloud hosting platform, you'll be able to activate this particular service easily for any of your domains. The Hepsia Control Panel, which is provided with the semi-dedicated accounts, has a very easy to use interface, so you do not have to be tech-savvy in order to protected your email addresses. You'll only have to type the hostname and the IP of each mail server that you'd like to be permitted to send e-mails from your addresses and shortly after that the new record will be active for the domain name that you've chosen. As a further option, we will also allow you to control the outgoing email messages and protect your mailboxes even better by permitting messages to be sent only when the domain name involved contains our MX records i.e. the email messages for the domain name should be handled by us and not by another supplier. Doing so you'll get even better control and there won't be any chance for anybody to forge your e-mails for harmful purposes.
