Sender Policy Framework, or SPF, is a validation system, that is designed to prevent the so-called email spoofing where an email message can be sent from one address, but to seem as being sent from another one, typically with the idea to fraud the recipient someway. When SPF protection is activated for a domain name, a unique record is generated for it in the Domain Name System and all the DNS servers around the world receive it. The record contains all of the email servers that are permitted to send valid messages from an address within the domain. When an email is sent, the very first DNS server it encounters verifies the SPF record and in case the sending server is permitted, the message is forwarded to the targeted receiver. If, however, the sending server is not present in the SPF record for the given domain, the e-mail message won't be forwarded and it'll be removed. When you employ this solution, it will prevent third parties from sending spam emails which look as if they have been sent by you.
SPF Protection in Cloud Website Hosting
You are able to enable the SPF protection option for your domain names with just a few clicks from the Hepsia Control Panel, which is included in all of our Linux cloud website hosting. This is performed from the section with the same name and you are able to enable the protection for each and every domain name hosted on our modern cloud hosting platform. Using a really intuitive interface, all you have to enter is the hostname of the mail server which will be permitted to send out messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you'll be able to add several servers as well, if needed. When your e-mails are managed by us, you may also use an even more secure option by setting a restriction that e-mail messages can be sent only when your domains feature our MX records. This solution can't be applied if your site is hosted here, while your emails are with some third-party provider. In either case, the SPF protection solution can greatly increase your web protection and stop others from spoofing your e-mail addresses.
SPF Protection in Semi-dedicated Servers
The SPF protection function is provided with all the Linux semi-dedicated plans, so in case you host your domains in an account on our cloud web hosting platform, you're able to activate the service effortlessly for all of your domain names. The Hepsia Control Panel, which comes as standard with the semi-dedicated accounts, has a very user-friendly interface, so you do not need to be proficient in the use of computers to protected your e-mails. You'll only need to type the hostname and the IP of each mail server that you would like to be certified to send emails from your addresses and immediately after that the new record will be active for the domain that you have chosen. As an additional option, we will also give you the ability to limit your outgoing email messages and protect your mailboxes further by allowing email messages to be sent only when the domain name in question features our MX records i.e. the e-mail messages for the domain name should be handled here and not by another company. Doing so you will get even better control and there won't be any chances for anybody to forge your e-mails for harmful objectives.
