SPF, which stands for Sender Policy Framework, is an e-mail security system, which is employed to validate if an email message is sent by a licensed server. Employing SPF protection for a domain will stop the counterfeiting of emails made with the domain. In simple words: enabling this attribute for a domain creates a specific record in the Domain Name System (DNS) containing the IP addresses of the servers which are allowed to send email messages from mail boxes using the domain. As soon as this record propagates worldwide, it exists on all the DNS servers that direct the Internet traffic. Every time an e-mail message is sent, the first DNS server it goes through verifies if it comes from an official server. When it does, it is forwarded to the destination address, but when it doesn't come from a server part of the SPF record for the particular domain, it is discarded. In this way nobody can mask an email address and make it appear as if you're sending spam messages. This approach is also identified as email spoofing.
SPF Protection in Shared Website Hosting
If you host your domain names in a shared website hosting account with us and we handle the email addresses for them, you are able to enable SPF protection for all of them with several clicks inside your Hepsia Control Panel. This service is available in a separate section where you'll be able to view which domain names are currently protected. For the ones that aren't, you will be able to enable the SPF protection solution and set up a lot of things at the same time - the hostnames of the mail servers that are permitted to send messages from your mailboxes, the IPv4 and IPv6 addresses of the servers, and even to create a rule that email messages can be sent only when your domains use our MX records. The aforementioned choice is the most secure one, and you can use it if we take care of the emails for your domain names and do not use another e-mail provider. The newly generated records will be activated within one day and nobody will be able to forge the FROM field in a message with your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
When you have a semi-dedicated server account from us, you are able to secure your emails by activating the SPF protection service for every domain hosted in your account with only a couple of clicks. This is done from the Emails section of our Hepsia Control Panel which is included with the semi-dedicated accounts and even in case you have no previous experience with these things, you will not have any kind of problems to activate the security. All that you will have to do will be to find a domain from a drop-down list and then type the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your e-mail addresses will be mailed around the world only if they're sent from that specific server. If your e-mail addresses are handled by us and not by some third-party provider, you can also use an option for e-mail messages to be mailed only when the domain contains our MX records and the latter would be the safest option. In case you have any kind of questions regarding thisfunction, you can get in touch with our support crew 24/7.
