Sender Policy Framework, or SPF, is a validation 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 look as being sent from a different, frequently with the objective to scam the recipient for some reason. When SPF protection is enabled for a domain, a special record is created for it in the Domain Name System and all the DNS servers worldwide receive it. The record includes all of the email servers that are allowed to send legitimate messages from an address within the domain. When an email is sent, the very first DNS server it goes to verifies the SPF record and when its sending server is permitted, the message is sent to the targeted destination. When, however, the sending server is not contained in the SPF record for the particular domain, the e-mail message won't be sent and it will be discarded. When you use this service, it'll prevent third parties from sending spam messages which look as if they have been sent by you.
SPF Protection in Shared Hosting
The SPF protection option is available by default with every single shared hosting plan that we supply and you will be able to use it with ease so that you can protect the email addresses for any domain hosted in your account. The service is handled through the Emails section of the hi-tech, albeit intuitive Hepsia Control Panel. What is needed to activate the protection is to type the IP of the mail server and its hostname -, for example. The moment the protection is activated, only this server will be able to send out e-mails from emails made under the domain that you have picked. Your e-mail addresses can be handled by another company, but if we handle them along with your site, you can also activate an option for your email messages to be sent only when the domain features our MX records. This selection provides you with improved security as solely our server will be approved to send emails from your mailboxes and you'll have better control. If you have any kind of questions or if you experience any sort of troubles with this service, you'll be able to contact our tech support team at any time and they will assist you immediately.
