SPF, which stands for Sender Policy Framework, is an email protection system, which is is intended to validate whether an email message is sent by an authorized server. Using SPF protection for a given domain name will stop the faking of email addresses generated with the domain. In simple words: activating this function for a domain name creates a specific record in the Domain Name System (DNS) that contains the IP addresses of the servers that are permitted to send e-mails from mail boxes under the domain. When this record propagates globally, it will exist on all DNS servers that route the Internet traffic. When an email message is sent, the first DNS server it uses checks whether it originates from an official server. If it does, it is forwarded to the destination address, yet when it doesn't originate from a server indexed in the SPF record for the domain, it's rejected. In this way nobody will mask an email address to make it appear as if you're e-mailing spam messages. This approach is also referred to as email spoofing.
SPF Protection in Web Hosting
If you host your domains in a web hosting account on our end and we handle the e-mail addresses for them, you are able to enable SPF protection for any of them with a couple of clicks inside your Hepsia Control Panel. The service can be found in a separate section where you are able to see which domain names are currently protected. For the ones that are not, you'll be able to activate the SPF protection solution and manage a number of things in the process - the hostnames of the mail servers that are permitted to send messages from your e-mails, the IPv4 and IPv6 addresses of the servers, as well as to create a rule that messages can be sent only if your domains have our MX records. The aforementioned choice is the most secure one, and you can use it if we take care of the e-mail addresses for your domains and you are not using some other email provider. The newly generated records will be activated within 24 hours and nobody will be able to forge the FROM field in an email using your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
If you have a semi-dedicated server account from our company, you will be able to secure your email addresses by enabling the SPF security service for every domain name hosted in your account with only a few mouse-clicks. You can do this from the Emails section of our Hepsia Control Panel which is provided with the semi-dedicated accounts and even when you have no previous experience with these things, you won't have any troubles to activate the security. The only things that you will have to do will be to select a domain name from a drop-down list and then type the mail server hostname and IPv4 or IPv6 address. As soon as the new record propagates, messages from your email addresses will be mailed around the world only if they were sent from that specific server. When your email addresses are handled by us and not by some third-party supplier, you can also activate an option for email messages to be mailed only when the domain includes our MX records and the aforementioned is the most secure option. When you have any kind of questions regarding thisfeature, you'll be able to get in touch with our technical support team 24/7.
