Sender Policy Framework, or SPF, is a verification system, which is used to stop the so-called e-mail spoofing where an e-mail message can be sent from one address, but to look as being sent from a different, often with the purpose to scam the recipient in some way. If SPF protection is activated for a domain, a unique record is created for it in the Domain Name System and all DNS servers worldwide get it. The record features all of the mail servers that are allowed to send legitimate messages from an email address under the domain. When a message is sent, the very first DNS server it goes to checks the SPF record and if its sending server is permitted, the message is sent to the target receiver. In case, however, the sending server doesn't exist in the SPF record for the particular domain, the e-mail message will not be sent and it'll be discarded. If you employ this solution, it will stop third parties from sending spam emails that look as if they have been sent by you.
SPF Protection in Shared Hosting
SPF protection can be enabled for every domain hosted in a shared hosting account on our cloud hosting platform with just a couple of clicks. The function is available in the Emails section of our modern Hepsia Control Panel and all you need to use it is to select one of your domains from the drop-down menu and then type in the hostnames as well as the IPv4 or IPv6 addresses of the email servers which will be authorized to send messages from your email addresses. As an additional option you may also restrict the e-mails to be sent from your domain only if it includes our MX records, i.e. if our servers handle the emails for it, not some third-party provider. This option gives you the best standard of protection, but it is not applicable in case only your web site is on our servers while your email addresses for the domain are managed in another place. Regardless, our SPF protection service will keep your emails safe from being used for spam and/or scam purposes.
SPF Protection in Semi-dedicated Servers
The SPF protection function is available with all of the semi-dedicated servers, so if you host your domain names in an account on our cloud website hosting platform, you can use the service easily for all of your domains. The Hepsia Control Panel, which is provided with the semi-dedicated accounts, features a quite easy to work with interface, so you do not need to be tech-savvy in order to secure your e-mails. You will simply need to type the hostname and the IP address of each mail server that you'd like to be certified to send out emails from your addresses and immediately after that the updated record will be active for the domain that you have selected. As an extra option, we also give you the ability to limit your outgoing email messages and secure your mailboxes further by permitting e-mail messages to be sent only if the domain in question has our MX records i.e. the email messages for the domain need to be handled here and not by another supplier. By doing so you'll enjoy even superior control and there will not be any chance for someone to forge your emails for malicious purposes.
