SPF, which is an acronym for Sender Policy Framework, is an e-mail security system, that is designed to confirm whether an email message was sent by an official server. Using SPF protection for a particular domain name will prevent the counterfeiting of email addresses created with the domain. In layman's terms: enabling this feature for a domain name creates a particular record in the Domain Name System (DNS) which contains the IP addresses of the servers that are permitted to send email messages from mail boxes under the domain. Once this record propagates globally, it exists on all the DNS servers that direct the Internet traffic. When a new e-mail message is sent, the first DNS server it uses checks if it originates from an approved server. If it does, it's forwarded to the destination address, but when it does not originate from a server listed in the SPF record for the particular domain, it is rejected. Thus nobody can mask an email address and make it appear as if you're e-mailing spam. This method is also referred to as email spoofing.
SPF Protection in Hosting
You are able to enable the SPF protection service for your domains with just a couple of clicks inside the Hepsia Control Panel, which is provided with all of our Linux hosting. This carried out from the section with the very same name and you can allow the protection for each domain name on our leading-edge cloud platform. Using a really convenient interface, all you'll have to type in 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. Of course, you'll be able to include several servers as well, when needed. If your emails are taken care of on our end, you can also employ an even more risk-free option by placing a restriction that e-mail messages can be sent only if your domains feature our MX records. This solution cannot be applied if your website is hosted here, but the e-mail addresses are with a third-party supplier. In either case, the SPF protection option will considerably enhance your web security and prevent other people from counterfeiting your e-mail addresses.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account with us, you'll be able to secure your email addresses by activating the SPF security service for every domain hosted in your account with only a couple of clicks. You can do this from the Emails section of our Hepsia Control Panel that is included with the semi-dedicated accounts and even if you have no previous practical experience with these kinds of things, you will not have any kind of difficulties to activate the protection. Everything that you'll need to do is to choose a domain from a drop-down menu and after that type the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your e-mail addresses will be delivered worldwide only if they were sent from that server. In case your e-mail addresses are managed by us and not by a third-party supplier, you will also be able to activate an option for e-mail messages to be sent only when the domain has our MX records and this is the most secure option. In case you have any questions regarding thisfunction, you will be able to get in touch with our technical support crew 24/7.
