Sender Policy Framework, or SPF, is a validation system, that is intended to prevent the so-called email spoofing where an email message can be sent from one email, but to seem as being sent from another, frequently with the purpose to fraud the recipient for some reason. When SPF protection is activated for a domain name, a special record is generated for it in the Domain Name System and all DNS servers around the world receive it. The record contains all the mail servers that are allowed to send valid messages from an address within the domain. When an e-mail is sent, the first DNS server it goes to checks the SPF record and when its sending server is permitted, the message is sent to the targeted receiver. When, however, the sending server doesn't exist in the SPF record for the specified domain, the e-mail message will not be submitted and it'll be discarded. If you use this solution, it will prevent third parties from sending spam e-mails which look as if they have been sent by you.
SPF Protection in Shared Website Hosting
You're able to enable the SPF protection service for your domains with just a few clicks in the Hepsia Control Panel, which comes with all our Linux shared website hosting. This is performed through the section bearing the very same name and you'll be able to set up the protection for each domain name on our state-of-the-art cloud platform. Using a very convenient interface, all you have to enter is the hostname of the mail server that will be approved to send messages from your e-mail addresses and its IPv4 or IPv6 address. Last, but not least, you're able to include several servers as well, if needed. In case your e-mail addresses are handled by us, you may also take advantage of a more secure option by putting a limit that email messages can be sent only if your domains feature our MX records. This option cannot be used in case your web site is here, and your emails are with some third-party provider. In either case, the SPF protection solution can strongly improve your web security and prevent other people from forging your email addresses.
SPF Protection in Semi-dedicated Servers
The SPF protection function is available with all of the Linux semi-dedicated hosting plans, so if you host your domains in an account on our cloud web hosting platform, you'll be able to activate this service effortlessly for all of your domains. The Hepsia Control Panel, which is provided with the semi-dedicated accounts, features a very easy to use interface, which means that you don't need to be tech-savvy to secure your email addresses. You will only have to type the hostname and the IP address of each mail server that you would like to be certified to send out emails from your addresses and immediately after that the new record will be activated for the domain name that you've chosen. As a further option, we will also allow you to limit your outgoing e-mail messages and secure your mailboxes even better by allowing e-mail messages to be sent only if the domain in question has our MX records i.e. the e-mail messages for the domain name have to be handled on our end and not by some other provider. By doing so you'll enjoy even better control and there will not be any chances for anyone to fake your e-mail addresses for harmful intentions.
