Sender Policy Framework, or SPF, is a verification system, which is employed to stop the so-called e-mail spoofing where an e-mail message can be sent from one email address, but to look as being sent from a different one, usually with the purpose to fraud the recipient in some way. If SPF protection is enabled for a domain, a specific record is generated for it in the Domain Name System and all DNS servers around the world receive it. The record includes all the mail servers that are permitted to send valid messages from an email address part of the domain. When a message is sent, the first DNS server it goes to verifies the SPF record and in case 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 sent and it will be removed. When you employ this service, it'll prevent third parties from sending spam e-mails which appear to have been sent by you.

SPF Protection in Cloud Hosting

You'll be able to activate the SPF protection service for your domains with only a couple of clicks from the Hepsia Control Panel, which is provided with our Linux cloud hosting. This is done from the section with an identical name and you can set up the protection for each domain on our outstanding cloud hosting platform. Using a very simple interface, all you'll need to enter is the hostname of the mail server which will be permitted to send messages from your email addresses and its IPv4 or IPv6 address. Of course, you're able to include several servers too, if needed. In case your email addresses are handled on our end, you may also use an even more secure option by putting a restriction that messages can be sent only if your domain names have our MX records. This option can't be applied if your website is hosted with us, while your email addresses are with some third-party service provider. Either way, the SPF protection option will strongly increase your web security and prevent other people from forging your email addresses.

SPF Protection in Semi-dedicated Servers

The Hepsia website hosting Control Panel, that comes as standard with all of our semi-dedicated servers, will provide you with an exceptionally intuitive interface to enable the SPF protection service for every domain that you host in your new account. A couple of clicks in the Emails section of Hepsia are enough for that and you will only have to type in the hostname and the IP address of the mail server that will be permitted to send messages from your e-mail addresses. In case the emails are managed by us and not by another supplier, you can raise the protection level even more and take advantage of an option for all the outgoing emails to be sent only if your domain names use our MX records. This option provides you with increased control and it will eliminate any chance of somebody faking your email addresses with the intention of spamming and / or scamming people. It is not applicable when only your site is hosted on our innovative cloud hosting platform, while your email addresses are handled by some other service provider. If you are not sure what options to select, our tech support team will assist you 24/7.
