SPF, which is short for Sender Policy Framework, is an email safety system, which is is intended to validate whether an e-mail message is sent by a certified server. Using SPF protection for a given domain name will prevent the forging of emails generated with the domain. In simple words: enabling this feature for a domain makes a special record in the Domain Name System (DNS) which includes the IP addresses of the servers which are allowed to send e-mail messages from mailboxes using the domain. The moment this record propagates globally, it will exist on all of the DNS servers that route the Internet traffic. Every time a new email message is sent, the first DNS server it goes through tests whether it comes from an accredited server. In the event it does, it is sent to the destination address, yet if it doesn't come from a server indexed in the SPF record for the particular domain, it is rejected. In this way nobody will be able to mask an e-mail address then make it look as if you're sending spam. This technique is also termed email spoofing.
SPF Protection in Cloud Website Hosting
SPF protection can be activated for any domain hosted in a cloud website hosting account on our cloud hosting platform with no more than a couple of mouse-clicks. The function can be found in the Emails section of our cutting-edge Hepsia Control Panel and all it takes to use it is to pick one of your domain names from the drop-down menu and then enter the hostnames plus the IPv4 or IPv6 addresses of the mail servers which will be authorized to send emails from your emails. As an added option you can also restrict the emails to be sent from your domain only if it includes our MX records, i.e. when our servers handle the e-mail addresses for it, not some third-party supplier. This solution offers you the top degree of security, but it is not applicable if only your site is on our servers while the email addresses for the domain name are handled in another place. Either way, the SPF protection service will keep your email addresses safe from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account from us, you will be able to secure your emails by enabling the SPF security service for every domain name in your account with only a few mouse-clicks. This can be done through the Emails section of the Hepsia Control Panel which comes with the semi-dedicated accounts and even when you have no previous practical experience with such matters, you will not have any problems to enable the security. Everything that you will have to do is to find a domain from a drop-down menu and after that type in the mail server hostname and IPv4 or IPv6 address. The moment the updated record propagates, messages from your email addresses will be sent around the world only if they're sent from that particular server. In case your email addresses are managed by us and not by some third-party provider, you will also be able to activate an option for email messages to be mailed only if the domain has our MX records and the aforementioned is the most secure option. When you have any kind of questions regarding thisfeature, you'll be able to get in touch with our technical support crew 24/7.
