Sender Policy Framework, or SPF, is a validation system, that is designed to prevent the so-called email spoofing where an e-mail message is sent from one email, but to appear as being sent from another one, generally with the idea to scam the recipient in some way. If SPF protection is enabled for a domain, a special record is created for it in the Domain Name System and all of the DNS servers worldwide have it. The record features all of the e-mail servers that are allowed to send legitimate messages from an address under the domain. When a message is sent, the very first DNS server it goes to verifies the SPF record and when the sending server is authorized, the message is forwarded to the target destination. If, however, the sending server is not present in the SPF record for the particular domain, the message won't be submitted and it'll be removed. When you use this solution, it will prevent third parties from sending spam messages which seem to have been sent by you.
SPF Protection in Hosting
The SPF protection option is accessible as standard with every single hosting plan that we supply and you'll be able to use it with ease so that you can secure the e-mail addresses for any domain hosted as part of your account. The service is controlled through the Emails section of our advanced, yet intuitive Hepsia Control Panel. All you need to activate the protection is to type in the IP of the e-mail server plus its hostname - mail.server.com, for instance. When the protection is activated, only this server will be able to send out e-mails from email addresses generated under the domain name that you've picked. Your email addresses may be managed by a different supplier, but when we handle them along with your site, you may also activate the option for your e-mails to be sent only if the domain features our MX records. This selection gives you superior protection as exclusively our server will be permitted to send emails from your mailboxes and you will have superior control. When you have any kind of questions or in case you experience any kind of difficulties with this service, you can contact our tech support team at any time and they'll assist you in a timely manner.
SPF Protection in Semi-dedicated Hosting
The SPF protection feature is provided with all the Linux semi-dedicated hosting, so when you host your domain names in an account on our cloud website hosting platform, you can use the service easily for all your domain names. The Hepsia Control Panel, which is provided with the semi-dedicated accounts, features a very user-friendly interface, which means that you won't have to be proficient in the use of computers to secure your emails. You'll simply need to type the hostname and the IP address of each mail server that you would like to be allowed to send out emails from your addresses and shortly after that the updated record will be active for the domain name that you have selected. As an extra option, we'll also give you the ability to limit your outgoing email messages and protect your mailboxes even better by allowing messages to be sent only when the domain in question includes our MX records i.e. the e-mail messages for the domain need to be managed here and not by another company. In this way you'll get even superior control and there won't be any chances for any person to forge your email addresses for malicious objectives.
