Sender Policy Framework, or SPF, is a verification system, that is designed to prevent the so-called e-mail spoofing where an email message is sent from one address, but to appear as being sent from another, generally with the objective to scam the recipient someway. If SPF protection is enabled for a domain, an exclusive record is made for it in the Domain Name System and all DNS servers worldwide get it. The record contains all the email servers that are allowed to send valid messages from an email address part of the domain. When a message is sent, the very first DNS server it encounters checks the SPF record and in case its sending server is permitted, the message is forwarded to the target receiver. In case, however, the sending server doesn't exist in the SPF record for the specified domain, the message will not be sent and it will be discarded. In case you employ this service, it will prevent third parties from sending spam messages which look as if they have been sent by you.
SPF Protection in Shared Web Hosting
The SPF protection feature is available as standard with each and every shared web hosting plan that we supply and you are able to use it with ease in order to secure the email addresses for any domain name hosted as part of your account. The service is controlled from the Emails section of the advanced, and easy to work with Hepsia Control Panel. All you need to activate the protection is to type in the IP of the mail server in addition to its hostname - mail.server.com, for example. When the protection is activated, only this server will be able to send e-mails from emails generated under the domain that you've selected. Your e-mails may be managed by some other supplier, but in case that we handle them along with your site, you can also enable an option for email messages to be sent only when the domain features our MX records. This selection gives you better protection as only our server will be approved to send out e-mail messages from your mailboxes and you will have better control. If you have any kind of questions or in case you experience any kind of problems with this service, you'll be able to contact our technical support team anytime and they will assist you in a timely manner.
