Sender Policy Framework, or SPF, is a validation system, which is designed to prevent the so-called e-mail spoofing where an email message can be sent from one email address, but to seem as being sent from another one, frequently with the idea to scam the recipient someway. If SPF protection is enabled for a domain, an exclusive record is generated for it in the Domain Name System and all of the DNS servers globally get it. The record features all the mail servers that are permitted to send legitimate messages from an email address part of the domain. When an e-mail is sent, the very first DNS server it encounters verifies the SPF record and in case its sending server is permitted, the message is sent to the target destination. If, however, the sending server is not included in the SPF record for the specified domain, the e-mail message won't be forwarded and it'll be removed. If you use this service, it'll prevent third parties from sending spam emails which appear to have been sent from you.

SPF Protection in Cloud Web Hosting

SPF protection can be activated for every domain name hosted in a cloud web hosting account on our cloud platform with no more than a couple of mouse-clicks. The option can be found in the Emails section of our innovative Hepsia Control Panel and all you need to activate it is to choose one of your domains from the drop-down menu and then type in the hostnames along with the IPv4 or IPv6 addresses of the mail servers which will be authorized to send email messages from your emails. As an additional option you can also restrict the emails to be sent from your domain name only when it includes our MX records, i.e. when our servers manage the e-mail addresses for it, not some third-party supplier. This feature provides you with the highest degree of safety, but it's not applicable if only your web site is on our servers while the e-mail addresses for the domain are taken care of in another place. Regardless, the SPF protection service will keep your emails risk-free from being used for spam or scam purposes.

SPF Protection in Semi-dedicated Hosting

When you have a semi-dedicated server account with us, you will be able to protect your emails by activating the SPF protection service for every domain name hosted in the account with only a couple of clicks. You can do this from the Emails section of the Hepsia Control Panel that is included with the semi-dedicated accounts and even if you have no previous practical experience with such matters, you will not have any troubles to enable the security. Everything that you will have to do is to pick a domain from a drop-down menu and then type the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your email addresses will be mailed globally only if they were sent from that server. In case your emails are handled by us and not by some third-party supplier, you will also be able to activate an option for e-mail messages to be sent only if the domain name contains our MX records and this would be the safest option. Should you have any questions regarding thisfeature, you will be able to get in touch with our technical support crew 24/7.
