Sender Policy Framework, or SPF, is a verification system, that is employed 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 another, usually with the objective to fraud the recipient in some way. If SPF protection is activated for a domain, a special record is generated for it in the Domain Name System and all of the DNS servers around the world have it. The record contains all the mail servers that are permitted to send valid messages from an email address part of the domain. When a message is sent, the very first DNS server it goes to checks the SPF record and if its sending server is authorized, the message is sent to the target receiver. In case, however, the sending server is not contained in the SPF record for the specified domain, the message won't be sent and it'll be removed. In the event that you employ this service, it'll stop third parties from sending spam emails which seem to have been sent by you.
SPF Protection in Cloud Hosting
The SPF protection feature is provided by default with every single cloud hosting plan that we offer and you are able to use it with ease to secure the emails for each domain name hosted in your account. The service is managed from the Emails section of our advanced, albeit easy-to-navigate Hepsia Control Panel. All it takes to activate the protection is to type in the IP address of the mail server plus its hostname - mail.server.com, for example. The moment the protection is activated, only this server will be able to send e-mails from emails generated under the domain name that you've selected. Your email addresses may be managed by a different supplier, but in case that we manage them in addition to your site, you can also enable the option for e-mail messages to be sent only when the domain has our MX records. This option provides you with even better security as solely our server will be authorized to send out e-mail messages from your mailboxes and you'll have improved control. If you have any kind of questions or if you experience any sort of problems with this particular service, you will be able to contact our technical support team at any time and they'll give you a hand in a timely manner.
