SPF, which means Sender Policy Framework, is an email protection system, which is is intended to verify if an email message was sent by a certified server. Using SPF protection for a given domain will prevent the forging of email addresses created with the domain. In simple words: enabling this function for a domain name generates a particular record in the Domain Name System (DNS) which includes the IP addresses of the servers that are permitted to send email messages from mailboxes under the domain. Once this record propagates globally, it will exist on all the DNS servers that route the Internet traffic. When some email message is sent, the initial DNS server it uses tests whether it comes from an authorized server. In the event it does, it's sent to the destination address, but if it does not come from a server part of the SPF record for the domain, it's rejected. Thus nobody will be able to mask an e-mail address to make it appear as if you're e-mailing spam. This approach is also known as email spoofing.
SPF Protection in Web Hosting
You are able to activate the SPF protection option for your domain names with a few clicks inside the Hepsia Control Panel, which is provided with all of our Linux web hosting service. This is performed via the section bearing an identical name and you'll be able to set up the protection for each domain name part of our hi-tech cloud platform. Using a very simple interface, all you'll need to submit is the hostname of the mail server that will be permitted to send out messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you are able to include several servers as well, if needed. If your e-mail addresses are handled by us, you can also take advantage of a more secure option by putting a restriction that emails can be sent only when your domains include our MX records. This alternative cannot be used if your website is hosted with us, while the email addresses are with some third-party service provider. Either way, the SPF protection solution will greatly improve your web security and prevent other people from counterfeiting your email addresses.
SPF Protection in Semi-dedicated Servers
The Hepsia website hosting Control Panel, which is provided with our Linux semi-dedicated hosting service, will provide you with a very easy-to-use interface to activate the SPF protection service for every domain name that you host within your new account. A few clicks in the Emails section of Hepsia will be enough for that and you will only have to enter the hostname and the IP address of the mail server that will be permitted to send out messages from your email addresses. When the e-mails are managed on our end and not by another provider, you're able to raise the protection level even further and activate an option for the outgoing emails to be sent only if your domains include our MX records. This option will provide you with more control and it'll eliminate any chance of someone counterfeiting your email addresses with the objective of spamming and scamming people. It's not applicable when only your web site is hosted on our state-of-the-art cloud web hosting platform, while your email addresses are handled by a different service provider. If you are not sure what features to select, our tech support staff will assist you 24/7.
