Sender Policy Framework, or SPF, is a verification system, that is employed to stop the so-called email spoofing where an email message is sent from one email, but to seem as being sent from another one, generally with the idea to fraud the recipient in some way. If SPF protection is enabled for a domain, a unique record is generated for it in the Domain Name System and all DNS servers worldwide receive it. The record contains all the e-mail servers that are permitted to send valid messages from an email address within the domain. When a message is sent, the very first DNS server it goes to checks the SPF record and when its sending server is permitted, the message is forwarded to the target destination. If, however, the sending server doesn't exist in the SPF record for the particular domain, the email message will not be forwarded and it'll be discarded. Whenever you use this solution, it'll prevent third parties from sending spam emails which seem to have been sent by you.
SPF Protection in Shared Web Hosting
SPF protection can be enabled for every domain name hosted in a shared web hosting account on our cloud 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 what is needed to enable it is to choose one of your domain names from a drop-down list and type in the hostnames and the IPv4 or IPv6 addresses of the mail servers that will be permitted to send email messages from your email addresses. As an additional option you can also restrict the email messages to be sent from your domain only when it has our MX records, i.e. when our servers manage the email addresses for it, not a third-party provider. This solution will provide you with the highest degree of protection, but it's not applicable when only your site is on our servers while the e-mail addresses for the domain name are handled somewhere else. Regardless, our SPF protection service will keep your email addresses protected from being used for spam or scam purposes.
SPF Protection in Semi-dedicated Hosting
The SPF protection feature is featured with all the Linux semi-dedicated hosting services, so when you host your domain names in an account on our cloud website hosting platform, you can activate this particular service with ease for all your domains. The Hepsia Control Panel, which is provided with the semi-dedicated accounts, features a really easy to use interface, therefore you will not have to be proficient in the use of computers in order to protected your emails. You will only have to type the hostname and the IP of each mail server that you would like to be certified to send emails from your addresses and immediately after that the updated record will be active for the domain name that you've selected. As a further option, we will also give you the ability to restrict the outgoing emails and protect your mailboxes further by allowing emails to be sent only when the domain name involved includes our MX records i.e. the email messages for the domain should be handled on our end and not by another supplier. By doing so you'll enjoy even better control and there will not be any chance for anyone to fake your e-mail addresses for malicious uses.
