SPF, which is an acronym for Sender Policy Framework, is an email security system, which is employed to verify whether an e-mail message is sent by a certified server. Employing SPF protection for a domain will prevent the faking of email addresses made with the domain. In simple words: activating this attribute for a domain name generates a special record in the Domain Name System (DNS) that contains the IP addresses of the servers that are allowed to send email messages from mailboxes under the domain. As soon as this record propagates globally, it will exist on all DNS servers that route the Internet traffic. Whenever an email message is sent, the first DNS server it goes through tests whether it originates from an official server. When it does, it is sent to the destination address, yet if it doesn't come from a server part of the SPF record for the domain, it's rejected. Thus nobody will mask an e-mail address and make it appear as if you're e-mailing spam messages. This method is also identified as email spoofing.
SPF Protection in Website Hosting
You can activate the SPF protection option for your domains with only a few clicks from the Hepsia Control Panel, which is included with all our Linux website hosting service. This is done via the section with an identical name and you're able to enable the protection for each domain on our revolutionary cloud platform. Using a very convenient interface, all you will have to enter is the hostname of the mail server that will be accredited to send messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you can include several servers as well, if needed. When your e-mails are taken care of on our end, you can also take advantage of an even more secure option by placing a restriction that e-mails can be sent only when your domain names feature our MX records. This alternative cannot be used when your website is here, but the e-mails are with some third-party provider. Either way, the SPF protection option will greatly enhance your web safety and stop others from counterfeiting your e-mail addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account from us, you will be able to secure your emails by activating the SPF protection service for any domain in your account with just a couple of clicks. You can do this in the Emails section of our Hepsia Control Panel which is included with the semi-dedicated accounts and even if you lack previous practical experience with such things, you won't have any kind of trouble to activate the security. All that you will need to do is to find a domain from a drop-down menu and after that type in the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your emails will be delivered worldwide only if they are sent from that particular server. If your emails are taken care of by us and not by some third-party supplier, you can also use an option for emails to be sent only if the domain contains our MX records and this is the most secure option. If you have any kind of questions about thisfeature, you will be able to contact our tech support crew 24/7.
