Sender Policy Framework, or SPF, is a validation system, which is employed to stop the so-called e-mail spoofing where an email message can be sent from one e-mail, but to seem as being sent from another, often with the idea to scam the recipient for some reason. When SPF protection is enabled for a domain, a specific record is created for it in the Domain Name System and all the DNS servers globally get it. The record contains all the email servers that are allowed to send legitimate messages from an address under the domain. When a message is sent, the very first DNS server it encounters checks the SPF record and in case its sending server is permitted, the message is forwarded to the targeted receiver. If, however, the sending server doesn't exist in the SPF record for the specified domain, the e-mail message will not be forwarded and it'll be removed. In the event that you use this solution, it will stop third parties from sending spam e-mails that seem to have been sent by you.
SPF Protection in Website Hosting
When you host your domain names in a website hosting account on our end and we manage the e-mails for them, you'll be able to activate SPF protection for all of them with several clicks inside your Hepsia Control Panel. The service can be found in its own section where you are able to view which domains are already secured. For those which aren't, you can enable the SPF protection solution and manage various things during the process - the hostnames of the mail servers that are allowed to send messages from your mailboxes, the IPv4 and IPv6 addresses of the servers, and even to create a rule that emails can be sent only if your domain names include our MX records. The last choice is the most secure one, but you can use it when we manage the emails for your domain names 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 fake the FROM field in a message by using your e-mail addresses.
SPF Protection in Semi-dedicated Servers
The SPF protection feature is featured with all semi-dedicated servers, so when you host your domain names in an account on our cloud website hosting platform, you're able to use the service with ease for any of your domain names. The Hepsia Control Panel, which is included with the semi-dedicated accounts, has a rather easy to use interface, so you won't have to be tech-savvy to secure your email addresses. You'll simply have to type the hostname and the IP of each mail server that you'd like to be authorized to send out e-mails from your addresses and immediately after that the new record will be activated for the domain name that you've chosen. As an extra option, we will also allow you to control the outgoing emails and secure your mailboxes even further by allowing email messages to be sent only when the domain in question has our MX records i.e. the email messages for the domain name need to be managed on our end and not by another supplier. By doing this you'll enjoy even better control and there won't be any chance for anybody to forge your e-mail addresses for malicious uses.
