Sender Policy Framework, or SPF, is a verification system, that is designed to prevent the so-called e-mail spoofing where an e-mail message is sent from one e-mail address, but to look as being sent from another one, ordinarily with the idea to scam the recipient for some reason. If SPF protection is enabled for a domain name, an exclusive record is made for it in the Domain Name System and all DNS servers around the world get it. The record contains all e-mail servers that are permitted to send valid messages from an e-mail address within the domain. When an email is sent, the very first DNS server it encounters checks the SPF record and in case its sending server is authorized, the message is forwarded to the targeted receiver. When, however, the sending server doesn't exist in the SPF record for the given domain, the e-mail message will not be submitted and it will be discarded. When you use this service, it'll stop third parties from sending spam which look as if they have been sent by you.
SPF Protection in Hosting
You are able to activate the SPF protection option for your domains with a couple of clicks inside the Hepsia Control Panel, which is provided with all our Linux hosting packages. This carried out via the section with the same name and you'll be able to enable the protection for any domain name part of our state-of-the-art cloud hosting platform. Using a very convenient interface, all you have to submit is the hostname of the mail server which will be approved to send messages from your email addresses and its IPv4 or IPv6 address. Of course, you'll be able to include several servers as well, when needed. In case your e-mails are managed on our end, you may also take advantage of a more risk-free option by setting a restriction that e-mail messages can be sent only when your domains feature our MX records. This solution cannot be used if your site is here, and the e-mail addresses are with some third-party service provider. Either way, the SPF protection option will vastly increase your online protection and prevent other people from counterfeiting your email addresses.
SPF Protection in Semi-dedicated Hosting
The SPF protection feature is provided with all Linux semi-dedicated packages, so if you host your domain names in an account on our cloud hosting platform, you can use this particular service with ease for any of your domains. The Hepsia Control Panel, which comes with the semi-dedicated accounts, has a very easy to work with interface, therefore you won't need to be tech-savvy in order to secure your email addresses. You'll only have to type the hostname and the IP of each mail server that you'd like to be certified to send e-mails from your addresses and immediately after that the new record will be active for the domain name that you have selected. As an extra option, we'll also allow you to restrict your outgoing email messages and secure your mailboxes even further by allowing e-mail messages to be sent only when the domain name in question includes our MX records i.e. the e-mail messages for the domain name have to be managed on our end and not by another supplier. Doing so you'll get even better control and there won't be any chance for someone to forge your email addresses for harmful purposes.
