Sender Policy Framework, or SPF, is a validation system, that is intended to stop the so-called e-mail spoofing where an email message can be sent from one address, but to appear as being sent from a different, often with the objective to fraud the recipient someway. When SPF protection is enabled for a domain, an exclusive record is made for it in the Domain Name System and all the DNS servers worldwide get it. The record includes all the mail servers that are permitted to send legitimate messages from an e-mail address under the domain. When an e-mail is sent, the very first DNS server it goes to checks the SPF record and when its sending server is authorized, the message is forwarded to the targeted destination. When, however, the sending server is not included in the SPF record for the specified domain, the e-mail message won't be sent and it will be discarded. If you use this solution, it'll stop third parties from sending spam which seem to have been sent from you.

SPF Protection in Cloud Web Hosting

When you host your domain names in a cloud web hosting account with us and we manage the e-mails for them, you will be able to activate SPF protection for them with several clicks in your Hepsia Control Panel. This service can be found in a section of its own where you'll be able to see which domains are currently secured. For the ones that are not, you can enable the SPF protection option and configure various things in the process - the hostnames of the mail servers that are permitted to send messages from your emails, the IPv4 and IPv6 addresses of the servers, and to create a rule that messages can be sent only if your domains have our MX records. The last choice is the most secure one, and it can be used in the event that we manage the e-mail addresses for your domains and do not use a different email supplier. The new records will propagate within 1 day and nobody will be able to fake the FROM field in a message with your e-mail addresses.

SPF Protection in Semi-dedicated Hosting

If you have a semi-dedicated server account from us, you can secure your email addresses by activating the SPF protection service for every domain in your account with just a few mouse-clicks. This is done from the Emails section of the Hepsia Control Panel which is provided with the semi-dedicated accounts and even if you lack previous experience with such matters, you won't have any trouble to enable the security. All that you'll have to do is to find a domain name from a drop-down menu and then type the mail server hostname and IPv4 or IPv6 address. As soon as the new record propagates, messages from your email addresses will be mailed worldwide only if they are sent from that particular server. If your e-mail addresses are handled by our company and not by some third-party provider, you can also benefit from an option for e-mail messages to be mailed only if the domain name has our MX records and the latter would be the safest option. When you have any kind of questions related to thisfeature, you will be able to get in touch with our support crew 24/7.
