Sender Policy Framework, or SPF, is a validation system, that is used to prevent the so-called e-mail spoofing where an e-mail message can be sent from one e-mail, but to appear as being sent from another, generally with the objective to scam the recipient someway. When SPF protection is activated for a domain, a special record is created for it in the Domain Name System and all of the DNS servers worldwide get it. The record includes all of the mail servers that are allowed to send authentic messages from an e-mail address under the domain. When a message is sent, the first DNS server it goes to checks the SPF record and when its sending server is permitted, the message is sent to the target receiver. If, however, the sending server doesn't exist in the SPF record for the particular domain, the e-mail message won't be sent and it'll be removed. If you use this service, it will prevent third parties from sending spam emails that appear 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 are able to use it without difficulty in order to secure the e-mails for each domain name hosted within your account. The service is operated from the Emails section of our advanced, yet intuitive Hepsia Control Panel. All you need to enable the protection is to type the IP of the mail server and its hostname -, for example. The moment the protection is active, only this server will be able to send out email messages from e-mails generated under the domain name that you've picked. Your e-mail addresses may be taken care of by some other supplier, but in case that we manage them together with your web site, you can also enable an option for e-mails to be sent only when the domain has our MX records. This option will provide you with superior protection as just our server will be authorized to send messages from your mailboxes and you will have improved control. When you have any kind of questions or if you experience any sort of issues with this particular service, you'll be able to contact our tech support team anytime and they'll help you in a timely manner.
