SPF, which is short for Sender Policy Framework, is an email security system, that is is intended to verify whether an email message is sent by an authorized server. Using SPF protection for a particular domain will stop the faking of emails created with the domain. In simple words: enabling this function for a domain creates a particular record in the Domain Name System (DNS) which contains the IP of the servers that are permitted to send e-mail messages from mail boxes using the domain. Once this record propagates worldwide, it will exist on all DNS servers that direct the Internet traffic. Any time an e-mail message is sent, the initial DNS server it goes through tests if it originates from an approved server. If it does, it is sent to the destination address, however when it does not come from a server listed in the SPF record for the domain, it is discarded. Thus nobody will mask an email address to make it look as if you are sending spam. This technique is also called email spoofing.
SPF Protection in Shared Hosting
The SPF protection feature is accessible by default with each and every shared hosting plan that we offer and you'll be able to use it with ease in order to protect the e-mails for each domain hosted within your account. The service is handled through the Emails section of our outstanding, yet easy-to-navigate 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 example. The moment the protection is active, only this server will be able to send e-mails from email addresses created under the domain that you've selected. Your emails may be managed by another company, but if we handle them together with your web site, you may also activate the option for emails to be sent only when the domain features our MX records. This option will provide you with improved protection as exclusively our server will be approved to send out messages from your mailboxes and you'll have superior control. When you have any kind of questions or in case you have any kind of difficulties with this service, you will be able to contact our technical support team anytime and they'll give you a hand immediately.
