Sender Policy Framework, or SPF, is a verification system, which is intended to prevent the so-called email spoofing where an e-mail message is sent from one e-mail address, but to appear as being sent from a different one, frequently with the purpose to fraud the recipient for some reason. If SPF protection is enabled for a domain name, an exclusive record is generated for it in the Domain Name System and all DNS servers around the world get it. The record includes all of the e-mail servers that are allowed to send valid messages from an email address under the domain. When an email is sent, the first DNS server it encounters verifies the SPF record and in case its sending server is permitted, the message is forwarded to the targeted destination. In case, however, the sending server is not contained in the SPF record for the given domain, the email message won't be submitted and it will be removed. When you use this service, it will stop third parties from sending spam e-mails that look as if they have been sent by you.

SPF Protection in Website Hosting

When you host your domains in a website hosting account on our end and we handle the e-mails for them, you'll be able to activate SPF protection for all of them with a few clicks inside your Hepsia Control Panel. The service is available in a separate section where you're able to see which domain names are currently protected. For the ones that are not, you will be able to enable the SPF protection service and set up a variety of things in the process - the hostnames of the mail servers that are allowed to send messages from your email addresses, the IPv4 and IPv6 addresses of these servers, as well as to create a rule that messages can be sent only if your domain names include our MX records. The last solution is the most secure one, but you can use it if we handle the e-mail addresses for your domain names and you're not using some other email provider. The newly created records will propagate within 1 day and nobody will be able to fake the FROM field in a message using your e-mail addresses.

SPF Protection in Semi-dedicated Servers

The SPF protection attribute is featured with all the Linux semi-dedicated hosting plans, so in case you host your domains in an account on our cloud web hosting platform, you'll be able to activate this particular service with ease for all of your domain names. The Hepsia Control Panel, which is provided with the semi-dedicated accounts, offers a very easy to use interface, therefore you will not have to be tech-savvy in order to secure your email addresses. You'll simply need to type the hostname and the IP of each mail server that you'd like to be certified to send e-mails from your addresses and right after that the new record will be activated for the domain that you have picked. As a further option, we will also allow you to limit the outgoing e-mail messages and protect your mailboxes even further by permitting email messages to be sent only when the domain in question includes our MX records i.e. the e-mail messages for the domain have to be taken care of here and not by a different provider. By doing this you'll have even better control and there will not be any chance for someone to counterfeit your e-mails for harmful objectives.
