Sender Policy Framework, or SPF, is a verification system, which is designed to stop the so-called email spoofing where an email message can be sent from one e-mail address, but to seem as being sent from another, generally with the idea to scam the recipient in some way. If SPF protection is enabled for a domain name, a special record is generated for it in the Domain Name System and all the DNS servers worldwide get it. The record contains all the mail servers that are allowed to send legitimate messages from an email address under the domain. When a message is sent, the very first DNS server it goes to verifies the SPF record and if its sending server is authorized, the message is sent to the targeted receiver. In case, however, the sending server is not present in the SPF record for the specified domain, the e-mail message won't be sent and it'll be discarded. In case you use this service, it'll prevent third parties from sending spam that seem to have been sent by you.

SPF Protection in Cloud Hosting

You're able to enable the SPF protection service for your domain names with just a couple of clicks inside the Hepsia Control Panel, which is provided with our Linux cloud hosting packages. This is performed from the section with the very same name and you can enable the protection for each domain name on our revolutionary cloud hosting platform. Using a really convenient interface, all you'll have to enter is the hostname of the mail server which will be permitted to send messages from your e-mail addresses and its IPv4 or IPv6 address. Of course, you can add several servers too, if needed. In case your e-mails are managed on our end, you may also take advantage of a more risk-free option by placing a limit that e-mails can be sent only when your domains have our MX records. This option can't be applied in case your site is hosted with us, while the e-mails are with some third-party provider. Either way, the SPF protection option can really increase your web security and stop others from spoofing your e-mail addresses.

SPF Protection in Semi-dedicated Hosting

If you have a semi-dedicated server account from our company, you are able to protect your email addresses by enabling the SPF security service for any domain name in the account with just a couple of clicks. This can be done in the Emails section of our Hepsia Control Panel that comes with the semi-dedicated accounts and even when you have no previous practical experience with these things, you won't have any kind of difficulties to activate the protection. The only things that you will need to do will be to select a domain from a drop-down list then type the mail server hostname and IPv4 or IPv6 address. When the updated record propagates, messages from your e-mail addresses will be delivered globally only if they are sent from that particular server. If your email addresses are handled by us and not by a third-party supplier, you can also take advantage of an option for emails to be mailed only if the domain contains our MX records and the aforementioned would be the most secure option.
