Sender Policy Framework, or SPF, is a verification system, which is used to stop the so-called e-mail spoofing where an email message is sent from one email address, but to appear as being sent from a different one, usually with the idea to fraud the recipient someway. When SPF protection is enabled for a domain name, an exclusive record is created for it in the Domain Name System and all the DNS servers around the world have it. The record features all the e-mail servers that are permitted to send legitimate messages from an address within the domain. When a message is sent, the very first DNS server it goes to verifies the SPF record and when its sending server is authorized, the message is sent to the targeted receiver. In case, however, the sending server is not included in the SPF record for the given domain, the message will not be forwarded and it'll be removed. Whenever you use this solution, it'll prevent third parties from sending spam that appear to have been sent from you.

SPF Protection in Hosting

You're able to activate the SPF protection option for your domains with a couple of clicks in the Hepsia Control Panel, which is included in all of our Linux hosting packages. This carried out via the section with the very same name and you are able to enable the protection for each domain name on our cutting-edge cloud platform. Using a really simple interface, all you'll need to submit is the hostname of the mail server that will be permitted to send messages from your emails and its IPv4 or IPv6 address. Last, but not least, it is possible to include several servers as well, if needed. If your e-mail addresses are managed by us, you can also take advantage of an even more risk-free option by placing a restriction that e-mail messages can be sent only if your domain names include our MX records. This alternative can't be applied if your site is here, while the email addresses are with a third-party supplier. Either way, the SPF protection solution can strongly enhance your web security and prevent others from counterfeiting your email addresses.

SPF Protection in Semi-dedicated Hosting

The Hepsia website hosting Control Panel, that is provided with all our Linux semi-dedicated packages, offers you a very easy-to-use interface to activate the SPF security service for each domain that you host within your new account. A couple of clicks in the Emails section of Hepsia will be enough for that then you'll only have to type in the hostname and the IP address of the mail server which will be permitted to send messages from your e-mails. If the e-mail messages are managed by us and not by some other supplier, you will be able to raise the protection level even more and benefit from an option for your outgoing e-mails to be sent only if your domains include our MX records. This option will provide you with more control and it'll eliminate any possibility of anyone counterfeiting your email addresses with the intention of spamming and / or scamming people. It's not applicable when only your site is on our modern cloud website hosting platform, while your e-mails are handled by another service provider. If you aren't sure what features to choose, our technical support staff will assist you 24/7.
