SPF, which is an acronym for Sender Policy Framework, is an e-mail security system, which is used to validate if an email message is sent by an authorized server. Employing SPF protection for a particular domain name will stop the counterfeiting of email addresses generated with the domain. In simple words: enabling this attribute for a domain name generates a special record in the Domain Name System (DNS) which includes the IP addresses of the servers that are allowed to send email messages 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 some e-mail message is sent, the first DNS server it uses verifies whether it originates from an accredited server. If it does, it is forwarded to the destination address, yet if it doesn't come from a server indexed in the SPF record for the domain, it is rejected. Thus nobody will mask an e-mail address then make it appear as if you are distributing spam. This approach is also termed email spoofing.
SPF Protection in Web Hosting
You can activate the SPF protection service for your domain names with only a couple of clicks in the Hepsia Control Panel, which is provided with our web hosting plans. This is done from the section bearing the same name and you'll be able to set up the protection for each domain name hosted on our cutting-edge cloud platform. Using a really user-friendly interface, all you will need to type in is the hostname of the mail server that will be approved to send messages from your e-mails and its IPv4 or IPv6 address. Of course, you are able to add several servers too, when needed. If your email addresses are managed by us, you can also employ an even more secure option by placing a limit that e-mails can be sent only if your domain names include our MX records. This option cannot be applied if your website is here, while the e-mails are with a third-party provider. In either case, the SPF protection option will considerably enhance your web protection and prevent others from spoofing your e-mail addresses.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account with us, you are able to secure your emails by activating the SPF protection service for any domain name hosted in your account with just a couple of clicks. This is done through the Emails section of our Hepsia Control Panel which is included with the semi-dedicated accounts and even when you have no previous practical experience with such things, you will not have any kind of trouble to activate the security. The only things that you will have to do will be to find a domain name from a drop-down list and after that type in the mail server hostname and IPv4 or IPv6 address. Once the updated record propagates, messages from your e-mail addresses will be mailed around the world only if they're sent from that particular server. In case your e-mail addresses are taken care of by us and not by some third-party supplier, you'll also be able to use an option for e-mail messages to be sent only when the domain includes our MX records and the aforementioned is the most secure option. Should you have any questions regarding thisfunction, you will be able to contact our tech support crew 24/7.
