Sender Policy Framework, or SPF, is a verification system, which is used to stop the so-called email spoofing where an e-mail message is sent from one address, but to seem as being sent from a different, often with the purpose to fraud the recipient for some reason. When SPF protection is activated for a domain, a unique record is made for it in the Domain Name System and all DNS servers globally get it. The record includes all the e-mail servers that are permitted to send valid 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 in case the sending server is permitted, the message is sent to the target destination. When, however, the sending server is not present in the SPF record for the particular domain, the e-mail message won't be submitted and it'll be discarded. In the event that you use this service, it will stop third parties from sending spam which look as if they have been sent from you.
SPF Protection in Website Hosting
SPF protection can be enabled for any domain name hosted in a website hosting account on our cloud hosting platform with no more than a few clicks. The option can be found in the Emails section of our state-of-the-art Hepsia Control Panel and all you need to enable it is to select one of your domain names from the drop-down list and to type in the hostnames together with the IPv4 or IPv6 addresses of the e-mail servers that will be authorized to send emails from your email addresses. As an added option you can even restrict the email messages to be sent from your domain only when it includes our MX records, in other words if our servers handle the emails for it, not some third-party provider. This feature will provide you with the top degree of protection, but it's not applicable when only your website is on our servers while your e-mail addresses for the domain name are handled elsewhere. In either case, our SPF protection service will keep your emails secure from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account with us, you'll be able to secure your emails by activating the SPF protection service for every domain name hosted in the account with just a few mouse-clicks. This can be done from the Emails section of our Hepsia Control Panel that is included with the semi-dedicated accounts and even in case you have no previous practical experience with these matters, you will not have any problems to enable the security. Everything that you will need to do is to choose a domain from a drop-down menu then type in the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your e-mail addresses will be mailed worldwide only if they are sent from that server. If your email addresses are handled by us and not by some third-party provider, you can also take advantage of an option for emails to be sent only when the domain features our MX records and this would be the safest option. When you have any questions regarding thisfeature, you can get in touch with our technical support crew 24/7.
