SPF, which means Sender Policy Framework, is an email security system, which is designed to validate if an e-mail message was sent by a licensed server. Employing SPF protection for a domain name will prevent the forging of email addresses generated with the domain. In simple words: activating this feature for a domain name makes a special record in the Domain Name System (DNS) that contains the IP addresses of the servers which are allowed to send e-mails from mail boxes under the domain. As soon as this record propagates worldwide, it will exist on all of the DNS servers that direct the Internet traffic. When an email message is sent, the first DNS server it uses verifies whether it originates from an approved server. If it does, it is forwarded to the destination address, but when it doesn't originate from a server part of the SPF record for the domain, it's rejected. Thus nobody can mask an e-mail address to make it appear as if you are sending spam messages. This technique is also referred to as email spoofing.
SPF Protection in Shared Hosting
When you host your domains in a shared hosting account with us and we handle the emails for them, you'll be able to enable SPF protection for all of them with a few clicks inside your Hepsia Control Panel. This service is available in its own section where you will be able to see which domains are currently secured. For the ones which aren't, you will be able to enable the SPF protection service and manage a number of things at the same time - the hostnames of the mail servers that are permitted to send messages from your addresses, the IPv4 and IPv6 addresses of these servers, and even to create a rule that emails can be sent only when your domain names have our MX records. The last mentioned solution is the most secure one, and it can be used when we take care of the email addresses for your domains and you are not using a different email supplier. The newly created records will be activated within 1 day and nobody will be able to forge the FROM field in an e-mail by using your addresses.
SPF Protection in Semi-dedicated Hosting
When you have a semi-dedicated server account from our company, you'll be able to secure your email addresses by enabling the SPF protection service for any domain in the account with only a couple of 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 practical experience with these issues, you won't have any kind of difficulties to enable the protection. All that you'll need to do is to pick a domain from a drop-down menu and after that type in the mail server hostname and IPv4 or IPv6 address. As soon as the updated record propagates, messages from your e-mail addresses will be sent globally only if they are sent from that server. In case your e-mail addresses are managed by our company and not by some third-party supplier, you'll also be able to take advantage of an option for email messages to be sent only if the domain name contains our MX records and the latter would be the most secure option. Should you have any kind of questions regarding thisfeature, you will be able to contact our tech support team 24/7.
