Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called e-mail spoofing where an e-mail message can be sent from one email, but to seem as being sent from a different one, ordinarily with the idea to scam the recipient for some reason. If SPF protection is activated for a domain, a unique record is created for it in the Domain Name System and all DNS servers around the world have it. The record includes all the email servers that are allowed to send authentic messages from an e-mail address under the domain. When a message is sent, the very first DNS server it encounters verifies the SPF record and in case the sending server is permitted, the message is sent to the target receiver. If, however, the sending server is not present in the SPF record for the given domain, the email message will not be forwarded and it'll be removed. Whenever you use this solution, it will prevent third parties from sending spam e-mails that look as if they have been sent by you.
SPF Protection in Website Hosting
If you host your domains in a website hosting account on our end and we handle the e-mails for them, you'll be able to enable SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. This service is available in a section of its own where you can see which domain names are already secured. For those that aren't, you will be able to activate the SPF protection solution and manage a lot of things during the process - the hostnames of the mail servers that are permitted to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of the servers, and even to create a rule that email messages can be sent only when your domains include our MX records. The aforementioned option is the most secure one, and you can use it if we take care of the email addresses for your domains and you are not using a different email supplier. The newly created records will propagate within 24 hours and nobody will be able to fake the FROM field in an email by using your email addresses.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account from our company, you'll be able to protect your emails by activating the SPF security service for any domain name in the account with only a few mouse-clicks. This can be done in the Emails section of the Hepsia Control Panel which is provided with the semi-dedicated accounts and even if you lack previous practical experience with these kinds of issues, you won't have any difficulties to enable the security. All that you will need to do is to pick a domain name from a drop-down list and then type the mail server hostname and IPv4 or IPv6 address. As soon as the updated record propagates, messages from your e-mail addresses will be mailed around the world only if they're sent from that particular server. In case your email addresses are handled by our company and not by some third-party provider, you will also be able to benefit from an option for e-mail messages to be sent only if the domain includes our MX records and the aforementioned would be the most secure option. In case you have any questions regarding thisfeature, you can contact our support team 24/7.
