Sender Policy Framework, or SPF, is a validation system, which is employed to prevent the so-called e-mail spoofing where an e-mail message can be sent from one e-mail address, but to look as being sent from another, typically with the objective to fraud the recipient for some reason. When SPF protection is activated for a domain name, an exclusive record is created for it in the Domain Name System and all the DNS servers worldwide have it. The record contains all the email servers that are allowed to send authentic messages from an address part of the domain. When a message is sent, the very first DNS server it encounters checks the SPF record and in case the sending server is permitted, the message is forwarded to the target receiver. When, however, the sending server doesn't exist in the SPF record for the particular domain, the email message won't be sent and it will be discarded. Whenever you use this solution, it will stop third parties from sending spam that seem to have been sent by you.
SPF Protection in Hosting
You're able to activate the SPF protection option for your domain names with only a few clicks in the Hepsia Control Panel, which comes with our hosting packages. This is done via the section bearing the same name and you are able to set up the protection for each and every domain name part of our leading-edge cloud platform. Using a very convenient interface, all you'll have to submit is the hostname of the mail server that will be permitted to send messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, you're able to add several servers too, if needed. If your e-mail addresses are handled on our end, you can also use an even more secure option by setting a restriction that email messages can be sent only if your domain names feature our MX records. This solution can't be used in case your site is hosted here, while the emails are with some third-party service provider. In either case, the SPF protection option can considerably increase your web safety and stop others from counterfeiting your email addresses.
SPF Protection in Semi-dedicated Hosting
The SPF protection feature is available with all of the Linux semi-dedicated hosting, so in case you host your domains in an account on our cloud hosting platform, you can activate the service with ease for all of your domain names. The Hepsia Control Panel, which comes with the semi-dedicated accounts, has a really easy to work with interface, which means that you do not have to be proficient in the use of computers in order to protected your e-mails. You'll only have to type the hostname and the IP address of each mail server that you would like to be permitted to send emails from your addresses and right after that the new record will be active for the domain name that you've picked. As a further option, we will also allow you to restrict the outgoing email messages and secure your mailboxes further by permitting messages to be sent only when the domain in question features our MX records i.e. the email messages for the domain need to be managed on our end and not by some other company. In this way you will get even better control and there won't be any chances for anyone to forge your email addresses for harmful uses.
