SPF, which is short for Sender Policy Framework, is an email safety system, that is used to verify whether an email message was sent by an authorized server. Employing SPF protection for a given domain will prevent the faking of emails made with the domain. In layman's terms: activating this attribute for a domain name makes a particular record in the Domain Name System (DNS) containing the IP addresses of the servers which are permitted to send email messages from mail boxes under the domain. The moment this record propagates worldwide, it will exist on all of the DNS servers that direct the Internet traffic. Every time a new email message is sent, the first DNS server it uses tests if it originates from an official server. If it does, it is forwarded to the destination address, yet if it does not originate from a server indexed in the SPF record for the domain, it's discarded. Thus nobody will be able to mask an e-mail address to make it look as if you are e-mailing spam messages. This method is also referred to as email spoofing.
SPF Protection in Shared Website Hosting
If you host your domains in a shared website hosting account with us and we handle the e-mail addresses for them, you are able to activate SPF protection for any of them with a couple of clicks inside your Hepsia Control Panel. This service is accessible in a separate section where you'll be able to see which domains are already secured. For those that aren't, you'll be able to activate 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, as well as to set a rule that emails can be sent only if your domains use our MX records. The last solution is the most secure one, but it can be used in the event that we take care of the e-mails for your domains and do not use another email supplier. The newly generated records will propagate within 24 hours and nobody will be able to forge the FROM field in a message by using your e-mail addresses.
