SPF, which stands for Sender Policy Framework, is an email safety system, that is is intended to confirm whether an e-mail message was sent by a certified server. Using SPF protection for a domain will prevent the counterfeiting of email addresses created with the domain. In simple words: enabling this feature for a domain name generates a particular record in the Domain Name System (DNS) which includes the IP of the servers which are allowed to send e-mails from mail boxes using the domain. The moment this record propagates worldwide, it will exist on all the DNS servers that direct the Internet traffic. Any time a new e-mail message is sent, the initial DNS server it goes through verifies if it comes from an official server. When it does, it is forwarded to the destination address, but if it doesn't originate from a server part of the SPF record for the particular domain, it is discarded. Thus nobody will mask an email address to make it appear as if you're sending spam messages. This approach is also known as email spoofing.
SPF Protection in Cloud Hosting
The SPF protection option is accessible as standard with each and every cloud hosting package that we supply and you'll be able to use it with ease to secure the e-mails for any domain hosted within your account. The service is controlled from the Emails section of the advanced, albeit intuitive Hepsia Control Panel. What is needed to enable the protection is to type in the IP of the mail server as well as its hostname - mail.server.com, for instance. The moment the protection is active, only this server will be able to send e-mail messages from e-mails generated under the domain name that you've picked. Your e-mail addresses can be handled by a different provider, but in case that we manage them in addition to your web site, you can enable the option for your messages to be sent only when the domain features our MX records. This feature gives you better security as only our server will be authorized to send emails from your mailboxes and you will have better control. When you have any questions or if you experience any sort of troubles with this service, you'll be able to contact our technical support crew at any time and they will assist you in a timely manner.
