SPF, which is short for Sender Policy Framework, is an e-mail security system, that is employed to validate whether an e-mail message was sent by a licensed server. Employing SPF protection for a domain name will stop the faking of email addresses generated with the domain. In simple words: activating this function for a domain generates a particular record in the Domain Name System (DNS) containing the IP of the servers which are allowed to send emails from mailboxes under the domain. As soon as this record propagates globally, it exists on all of the DNS servers that route the Internet traffic. Whenever some e-mail message is sent, the initial DNS server it goes through verifies whether it originates from an approved server. In the event it does, it is sent to the destination address, however when it doesn't come from a server listed in the SPF record for the domain, it is discarded. Thus nobody can mask an email address then make it appear as if you're sending spam. This approach is also identified as email spoofing.
SPF Protection in Shared Hosting
If you host your domain names in a shared hosting account on our end and we handle the email addresses for them, you will be able to enable SPF protection for them with a few clicks inside your Hepsia Control Panel. This service is accessible in a separate section where you can view which domains are already protected. For those that are not, you'll be able to enable the SPF protection service and configure various things at the same time - the hostnames of the mail servers that are permitted to send messages from your email addresses, the IPv4 and IPv6 addresses of these servers, and even to create a rule that email messages can be sent only if your domains have our MX records. The last mentioned choice is the most secure one, and it can be used if we take care of the emails for your domains and you are not using some other e-mail provider. The new records will propagate within a 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
The Hepsia hosting Control Panel, which is included with our Linux semi-dedicated hosting packages, offers you an incredibly easy-to-use interface to activate the SPF security service for any domain name that you host in your new account. Several clicks in the Emails section of Hepsia will be enough for that then you'll only have to enter the hostname and the IP address of the mail server that will be permitted to send messages from your emails. If the emails are taken care of by us and not by another provider, you are able to increase the security level even further and benefit from an option for the outgoing e-mail messages to be sent only if your domains use our MX records. This option will give you better control and it will eliminate any possibility of anybody counterfeiting your e-mails with the objective of spamming or scamming people. It is not applicable if just your site is hosted on our innovative cloud hosting platform, while your e-mail addresses are handled by another service provider. If you are not sure what options to pick, our technical support crew will assist you 24/7.
