Sender Policy Framework, or SPF, is a validation system, which is employed to prevent the so-called e-mail spoofing where an email message can be sent from one e-mail, but to look as being sent from another one, often with the idea to fraud the recipient someway. If SPF protection is activated for a domain, an exclusive record is made for it in the Domain Name System and all DNS servers around the world get it. The record features all the mail servers that are permitted to send legitimate messages from an email address part of the domain. When an email is sent, the first DNS server it goes to 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 contained in the SPF record for the specified domain, the email message will not be forwarded and it will be removed. When you employ this service, it will stop third parties from sending spam emails which seem to have been sent from you.
SPF Protection in Website Hosting
If you host your domain names in a website hosting account on our end and we handle the e-mail addresses for them, you will be able to enable SPF protection for any of them with a couple of clicks in your Hepsia Control Panel. This service is available in its own section where you are able to see which domains are currently protected. For those which aren't, you can enable the SPF protection service and configure a variety of things at the same time - the hostnames of the mail servers that are allowed to send messages from your emails, the IPv4 and IPv6 addresses of the servers, and even to create a rule that email messages can be sent only when your domains have our MX records. The aforementioned option is the most secure one, and you can use it if we take care of the e-mail addresses for your domain names and do not use some other e-mail provider. The newly created records will be activated within one day and nobody will be able to forge the FROM field in an e-mail using your addresses.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account from our company, you are able to secure your emails by activating the SPF protection service for any domain name hosted in the account with just a couple of clicks. This can be done from the Emails section of our Hepsia Control Panel that is provided with the semi-dedicated accounts and even in case you have no previous experience with these things, you will not have any trouble to enable the protection. The only things that you will need 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. When the new record propagates, messages from your e-mail addresses will be mailed globally only if they were sent from that particular server. In case your email addresses are managed by our company and not by a third-party supplier, you'll also be able to activate an option for email messages to be mailed only when the domain name has our MX records and the latter is the most secure option. In case you have any kind of questions related to thisfeature, you will be able to get in touch with our tech support team 24/7.
