SPF, which means Sender Policy Framework, is an email security system, which is designed to validate if an email message was sent by an official server. Using SPF protection for a domain name will prevent the counterfeiting of email addresses made with the domain. In simple words: activating this function for a domain creates a specific record in the Domain Name System (DNS) which contains the IP addresses of the servers that are permitted to send e-mail messages from mail boxes using the domain. The moment this record propagates worldwide, it exists on all DNS servers that route the Internet traffic. When an e-mail message is sent, the first DNS server it goes through verifies if it originates from an accredited server. If it does, it's sent to the destination address, but when it does not come from a server part of the SPF record for the particular domain, it's rejected. In this way nobody will be able to mask an e-mail address then make it appear as if you're e-mailing spam messages. This method is also called email spoofing.
SPF Protection in Shared Hosting
The SPF protection feature is available as standard with each shared hosting plan that we supply and you'll be able to use it without any difficulty to secure the emails for any domain hosted as part of your account. The service is handled from the Emails section of our outstanding, albeit easy to work with Hepsia Control Panel. All it takes to activate the protection is to type the IP address of the email server as well as its hostname - mail.server.com, for example. When the protection is active, only this server will be able to send out e-mails from emails made under the domain that you have picked. Your emails can be taken care of by some other company, but if we take care of them together with your site, you may also activate the option for your messages to be sent only when the domain features our MX records. This solution provides you with better protection as exclusively our server will be permitted to send messages from your mailboxes and you'll have better control. When you have any questions or if you have any kind of problems with this particular service, you will be able to contact our tech support crew at any time and they'll help you in a timely manner.
SPF Protection in Semi-dedicated Hosting
The Hepsia website hosting Control Panel, that comes with our Linux semi-dedicated hosting packages, provides you with an extremely user-friendly interface to activate the SPF security service for each domain name that you host in your new account. Just a few clicks in the Emails section of Hepsia are enough for that and you'll only have to enter the hostname and the IP address of the mail server which will be allowed to send out messages from your emails. If the email messages are managed by us and not by some other provider, you can raise the protection level even further and benefit from an option for the outgoing e-mail messages to be sent only if your domain names feature our MX records. This option will give you increased control and it'll eliminate any possibility of someone counterfeiting your emails with the objective of spamming and scamming people. It is not applicable when only your site is hosted on our cutting-edge cloud web hosting platform, while your e-mails are managed by another provider. If you aren't sure what options to pick, our technical support team will help you 24/7.
