Sender Policy Framework, or SPF, is a verification system, that is designed to stop the so-called email spoofing where an e-mail message can be sent from one address, but to seem as being sent from a different, often with the purpose to scam the recipient someway. When SPF protection is activated for a domain, a unique record is created for it in the Domain Name System and all of the DNS servers globally get it. The record includes all the mail servers that are permitted to send authentic messages from an address under the domain. When a message is sent, the very first DNS server it encounters verifies the SPF record and when its sending server is permitted, the message is forwarded to the targeted destination. If, however, the sending server is not present in the SPF record for the given domain, the e-mail message will not be forwarded and it will be removed. If you employ this solution, it will stop third parties from sending spam messages that seem to have been sent by you.
SPF Protection in Shared Web Hosting
SPF protection can be enabled for each domain hosted in a shared web hosting account on our cloud hosting platform with just a few mouse-clicks. The feature is accessible in the Emails section of our advanced Hepsia Control Panel and what is needed to enable it is to select one of your domains from a drop-down menu and type in the hostnames together with the IPv4 or IPv6 addresses of the e-mail servers that will be certified to send messages from your email addresses. As an additional option you can even restrict the e-mails to be sent from your domain only if it has our MX records, in other words when our servers handle the email addresses for it, not a third-party supplier. This solution will provide you with the top level of protection, but it's not applicable when only your web site is on our servers while the email addresses for the domain name are managed in a different place. Either way, our SPF protection service will keep your email addresses protected from being used for spam and/or scam purposes.
SPF Protection in Semi-dedicated Servers
The SPF protection attribute is available with all Linux semi-dedicated servers, so if you host your domain names in an account on our cloud website hosting platform, you can activate this particular service effortlessly for all your domains. The Hepsia Control Panel, which comes as standard with the semi-dedicated accounts, has a rather intuitive interface, which means that you do not need to be tech-savvy to protected your e-mail addresses. You will simply need to type the hostname and the IP address of each mail server that you would like to be permitted to send emails from your addresses and shortly after that the new record will be activated for the domain name that you've picked. As an extra option, we will also give you the ability to restrict your outgoing email messages and secure your mailboxes further by allowing emails to be sent only if the domain in question includes our MX records i.e. the emails for the domain need to be handled here and not by a different company. Doing so you will enjoy even superior control and there won't be a chance for any person to forge your e-mail addresses for harmful purposes.
