SPF, which is short for Sender Policy Framework, is an e-mail security system, that is designed to confirm whether an e-mail message is sent by a certified server. Employing SPF protection for a particular domain will prevent the forging of email addresses generated with the domain. In simple words: activating this feature for a domain generates a specific record in the Domain Name System (DNS) which includes the IP addresses of the servers which are permitted to send email messages from mail boxes using the domain. The moment this record propagates globally, it exists on all of the DNS servers that route the Internet traffic. Every time some e-mail message is sent, the initial DNS server it goes through tests whether it originates from an official server. If it does, it is sent to the destination address, but if it doesn't originate from a server listed in the SPF record for the domain, it's rejected. In this way nobody can mask an e-mail address then make it look as if you are e-mailing spam messages. This method is also identified as email spoofing.
SPF Protection in Shared Hosting
You are able to activate the SPF protection service for your domain names with just a few clicks in the Hepsia Control Panel, which comes with our Linux shared hosting. This is performed through the section with the same name and you are able to allow the protection for any domain name on our modern cloud platform. Using a very convenient 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-mail addresses and its IPv4 or IPv6 address. Last, but not least, you'll be able to add several servers as well, if needed. When your e-mail addresses are taken care of on our end, you may also employ a more secure option by placing a restriction that e-mails can be sent only when your domain names have our MX records. This option can't be used when your site is hosted with us, but your email addresses are with some third-party service provider. Either way, the SPF protection option will tremendously increase your online safety and prevent other people from forging your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
The Hepsia web hosting Control Panel, which comes with our Linux semi-dedicated hosting, will provide you with an incredibly intuitive interface to enable the SPF protection service for every domain that you host within your new account. A few clicks in the Emails section of Hepsia are enough for that and you'll only have to type in the hostname and the IP address of the mail server that will be permitted to send messages from your emails. In case the emails are taken care of on our end and not by a different provider, you're able to boost the security level even more and activate an option for your outgoing emails to be sent only if your domain names feature our MX records. This option provides you with better control and it'll eliminate any chance of anyone forging your e-mails with the objective of spamming and scamming people. It's not applicable in case just your site is hosted on our modern cloud website hosting platform, while your email addresses are managed by another service provider. If you are not sure what options to choose, our technical support staff will assist you 24/7.
