Sender Policy Framework, or SPF, is a validation system, that is used to stop the so-called e-mail spoofing where an email message is sent from one e-mail, but to seem as being sent from a different, generally with the purpose to scam the recipient in some way. If SPF protection is activated for a domain name, a specific record is made for it in the Domain Name System and all of the DNS servers globally get it. The record features all of the mail servers that are allowed to send authentic messages from an email address part of the domain. When an email is sent, the first DNS server it encounters checks the SPF record and in case the sending server is authorized, the message is forwarded to the target destination. In case, however, the sending server is not present in the SPF record for the specified domain, the message won't be forwarded and it will be removed. Whenever you employ this solution, it will prevent third parties from sending spam emails that look as if they have been sent by you.
SPF Protection in Hosting
The SPF protection feature is provided by default with each and every hosting plan that we supply and you will be able to use it with ease in order to protect the e-mail addresses for each domain hosted within your account. The service is handled through the Emails section of the cutting-edge, and intuitive Hepsia Control Panel. What is needed to enable the protection is to type in the IP address of the mail server as well as its hostname - mail.server.com, for example. Once the protection is activated, only this server will be able to send e-mail messages from email addresses created under the domain that you've selected. Your emails may be managed by a different provider, but in case that we handle them along with your web site, you can activate the option for your emails to be sent only if the domain has our MX records. This feature gives you improved protection as only our server will be authorized to send e-mail messages from your mailboxes and you will have superior control. If you have any questions or if you experience any problems with this service, you will be able to contact our tech support crew anytime and they'll help you immediately.
