Sender Policy Framework, or SPF, is a validation system, that is employed to prevent the so-called e-mail spoofing where an email message can be sent from one address, but to appear as being sent from another one, usually with the idea to scam the recipient in some way. If SPF protection is enabled for a domain name, a specific record is created for it in the Domain Name System and all of the DNS servers worldwide have it. The record contains all mail servers that are allowed to send valid messages from an e-mail 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 targeted destination. If, however, the sending server is not included in the SPF record for the given domain, the e-mail message won't be forwarded and it'll be discarded. In the event that you use this solution, it'll prevent third parties from sending spam that look as if they have been sent by you.

SPF Protection in Cloud Website Hosting

SPF protection can be enabled for any domain hosted in a cloud website hosting account on our cloud hosting platform with only a few clicks. The feature can be found in the Emails section of our cutting-edge Hepsia Control Panel and what is needed to enable it is to choose one of your domain names from the drop-down menu and to type in the hostnames and the IPv4 or IPv6 addresses of the email servers that will be permitted to send messages from your email addresses. As an added option you can also restrict the messages to be sent from your domain name only when it has our MX records, i.e. if our servers handle the email addresses for it, not a third-party provider. This solution offers you the top level of safety, but it's not applicable when only your web site is on our servers while the e-mail addresses for the domain name are taken care of in a different place. In either case, the SPF protection service will keep your email addresses safe from being used for spam and/or scam purposes.

SPF Protection in Semi-dedicated Servers

The SPF protection function comes with all of the semi-dedicated hosting plans, so if you host your domains in an account on our cloud website hosting platform, you can activate this service easily for any of your domain names. The Hepsia Control Panel, which is included with the semi-dedicated accounts, has a really user-friendly interface, which means that you will not have to be tech-savvy to protected your e-mail addresses. You'll simply need to type the hostname and the IP of each mail server that you'd like to be permitted to send out e-mails from your addresses and shortly after that the new record will be active for the domain name that you have chosen. As an additional option, we also give you the ability to restrict the outgoing emails and protect your mailboxes further by permitting email messages to be sent only if the domain name involved contains our MX records i.e. the email messages for the domain name have to be taken care of on our end and not by some other supplier. Thus you will have even superior control and there won't be a chance for anyone to counterfeit your e-mail addresses for malicious objectives.
