SPF, which means Sender Policy Framework, is an e-mail protection system, which is used to validate whether an email message was sent by a certified server. Employing SPF protection for a given domain name will prevent the forging of email addresses created with the domain. In simple words: activating this function for a domain name makes a particular record in the Domain Name System (DNS) containing the IP addresses of the servers which are allowed to send emails from mail boxes using the domain. The moment this record propagates worldwide, it will exist on all DNS servers that direct the Internet traffic. Whenever an email message is sent, the initial DNS server it uses verifies if it originates from an approved server. When it does, it's sent to the destination address, but if it does not originate from a server listed 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 e-mailing spam messages. This method is also identified as email spoofing.
SPF Protection in Cloud Website Hosting
You'll be able to activate the SPF protection option for your domain names with just a few clicks in the Hepsia Control Panel, which comes with all of our cloud website hosting plans. This is done through the section with the very same name and you can enable the protection for each and every domain hosted on our outstanding cloud platform. Using a really convenient interface, all you will need to submit is the hostname of the mail server that will be authorized 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 employ a more secure option by putting a restriction that emails can be sent only when your domain names feature our MX records. This alternative can't be used when your site is here, and your email addresses are with some third-party provider. In either case, the SPF protection solution can considerably increase your web safety and prevent others from spoofing your e-mail addresses.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account from our company, you'll be able to secure your email addresses by enabling the SPF security service for every domain name hosted in the account with just a couple of clicks. This can be done in the Emails section of our Hepsia Control Panel which comes with the semi-dedicated accounts and even in case you have no previous experience with these kinds of things, you will not have any trouble to enable the protection. All that you'll need to do is to choose a domain name from a drop-down menu then type in the mail server hostname and IPv4 or IPv6 address. As soon as the updated record propagates, messages from your email addresses will be delivered around the world only if they're sent from that particular server. If your email addresses are handled by our company and not by some third-party provider, you'll also be able to take advantage of an option for e-mail messages to be sent only when the domain has our MX records and this would be the most secure option. Should you have any kind of questions regarding thisfunction, you can contact our technical support crew 24/7.
