Sender Policy Framework, or SPF, is a validation system, that is employed to prevent the so-called email spoofing where an e-mail message is sent from one address, but to look as being sent from a different one, often with the purpose to fraud the recipient for some reason. If SPF protection is activated for a domain, a unique record is created for it in the Domain Name System and all the DNS servers globally receive it. The record includes all the mail servers that are permitted to send valid messages from an email address within the domain. When an e-mail is sent, the first DNS server it goes to checks the SPF record and if the sending server is authorized, the message is forwarded to the targeted destination. If, however, the sending server is not included in the SPF record for the particular domain, the e-mail message will not be sent and it will be discarded. When you use this solution, it'll prevent third parties from sending spam messages that seem to have been sent from you.
SPF Protection in Cloud Hosting
SPF protection can be activated for any domain name hosted in a cloud hosting account on our cloud hosting platform with no more than a couple of clicks. The function can be found in the Emails section of our state-of-the-art Hepsia Control Panel and all you need to use it is to choose one of your domain names from a drop-down menu and to type in the hostnames together with the IPv4 or IPv6 addresses of the email servers which will be certified to send emails from your emails. As an added option you may also restrict the messages to be sent from your domain name only if it includes our MX records, i.e. when our servers handle the e-mail addresses for it, not some third-party supplier. This option will provide you with the top degree of safety, but it is not applicable if only your website is on our servers while your emails for the domain name are taken care of in another place. Regardless, the SPF protection service will keep your emails protected from being used for spam and/or scam purposes.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account from us, you are able to protect your email addresses by enabling the SPF protection service for every domain name in the account with just a couple of mouse-clicks. This can be done in the Emails section of the Hepsia Control Panel which is included with the semi-dedicated accounts and even if you have no previous practical experience with such things, you will not have any kind of trouble to activate the security. All that you will have to do is to find a domain name from a drop-down list and after that type the mail server hostname and IPv4 or IPv6 address. When the updated record propagates, messages from your e-mail addresses will be delivered worldwide only if they are sent from that server. If your email addresses are managed by our company and not by a third-party supplier, you can also activate an option for email messages to be sent only when the domain name contains our MX records and this would be the safest option. When you have any kind of questions regarding thisfeature, you'll be able to get in touch with our support crew 24/7.
