Sender Policy Framework, or SPF, is a verification system, which is employed to stop the so-called email spoofing where an e-mail message can be sent from one address, but to appear as being sent from a different one, often with the idea to scam the recipient in some way. If SPF protection is activated for a domain name, a special record is made for it in the Domain Name System and all the DNS servers around the world get it. The record contains all e-mail servers that are permitted to send valid messages from an e-mail address part of the domain. When an email is sent, the very first DNS server it goes to checks the SPF record and when the sending server is permitted, the message is forwarded to the targeted destination. In case, however, the sending server is not contained in the SPF record for the given domain, the message won't be submitted and it'll be discarded. If you use this service, it'll stop third parties from sending spam messages which seem to have been sent from you.
SPF Protection in Shared Web Hosting
SPF protection can be activated for every domain hosted in a shared web hosting account on our cloud hosting platform with no more than a couple of mouse-clicks. The function is accessible in the Emails section of our innovative Hepsia Control Panel and all it takes to enable it is to pick one of your domain names from the drop-down list and to enter the hostnames as well as the IPv4 or IPv6 addresses of the mail servers that will be authorized to send messages from your emails. As an added option you can also restrict the email messages to be sent from your domain name only when it includes our MX records, i.e. when our servers manage the e-mail addresses for it, not some third-party supplier. This option provides you with the highest standard of safety, but it's not applicable if only your web site is on our servers while your email addresses for the domain name are managed elsewhere. Regardless, the SPF protection service will keep your email addresses secure from being used for spam and/or scam purposes.
SPF Protection in Semi-dedicated Servers
When you host your domain names in a semi-dedicated server account from us, you will be able to employ the SPF protection feature as a part of the standard set of services that you will have with this type of hosting. Enabling the protection will require just several easy steps within the Hepsia Control Panel, thus even if you haven't employed such a feature before, you will not have any problems. Using a really easy-to-navigate interface, you'll just have to input the information of the mail server which will be authorized to send messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the recently generated record propagates, nobody will be able to fake any e-mail for that particular domain name and send emails from a server other than the one you've typed in. This doesn't specifically have to be our mail server, however in case we handle your email messages, you will be able to allow an extra level of protection by selecting an option that email messages can be send from addresses @your-domain.com only in the event that the domain uses our MX records. Our technical support staff will be able to assist you 24/7 in case you have any kind of questions regarding this service.
