Sender Policy Framework, or SPF, is a verification system, which is employed to stop the so-called e-mail spoofing where an e-mail message is sent from one address, but to look as being sent from another one, usually with the objective to scam the recipient someway. When SPF protection is activated for a domain, a unique record is made for it in the Domain Name System and all DNS servers globally have it. The record features all the mail servers that are allowed to send legitimate messages from an e-mail address under the domain. When a message is sent, the first DNS server it goes to checks the SPF record and in case its sending server is authorized, the message is forwarded to the target receiver. When, however, the sending server is not contained in the SPF record for the particular domain, the email message won't be submitted and it will be discarded. When you employ this service, it will stop third parties from sending spam messages which look as if they have been sent from you.
SPF Protection in Shared Hosting
The SPF protection option is provided as standard with each and every shared hosting package that we offer and you can use it without difficulty so that you can secure the e-mail addresses for each domain name hosted within your account. The service is handled from the Emails section of our hi-tech, albeit intuitive Hepsia Control Panel. What is needed to enable the protection is to type the IP address of the e-mail server plus its hostname -, for example. Once the protection is activated, only this server will be able to send out e-mail messages from e-mails created under the domain that you've picked. Your email addresses may be handled by some other provider, but in case that we manage them in addition to your website, you can also activate the option for emails to be sent only when the domain uses our MX records. This selection gives you greater security as only our server will be approved to send out messages from your mailboxes and you'll have improved control. If you have any questions or in case you have any problems with this particular service, you'll be able to contact our tech support crew at any time and they'll help you in a timely manner.
