Sender Policy Framework, or SPF, is a verification system, which is employed to prevent the so-called e-mail spoofing where an email message is sent from one email address, but to seem as being sent from another one, generally with the objective to fraud the recipient someway. When SPF protection is activated for a domain name, a specific record is created for it in the Domain Name System and all of the DNS servers globally get it. The record contains all of the e-mail servers that are permitted to send authentic messages from an email address within the domain. When an e-mail is sent, the very first DNS server it goes to checks the SPF record and in case its sending server is permitted, the message is forwarded to the target receiver. If, however, the sending server is not included in the SPF record for the specified domain, the message won't be forwarded and it will be removed. If you use this service, it'll stop third parties from sending spam that appear to have been sent from you.
SPF Protection in Cloud Hosting
If you host your domains in a cloud hosting account with us and we handle the e-mail addresses for them, you are able to activate SPF protection for them with a couple of clicks inside your Hepsia Control Panel. The service is available in its own section where you will be able to see which domains are currently protected. For those that are not, you'll be able to enable the SPF protection solution and configure numerous things during the process - the hostnames of the mail servers that are permitted to send messages from your emails, the IPv4 and IPv6 addresses of the servers, and to set a rule that emails can be sent only if your domain names include our MX records. The aforementioned choice is the most secure one, but it can be used when we take care of the e-mail addresses for your domains and you're not using another email provider. The newly generated records will propagate within 1 day and nobody will be able to forge the FROM field in an e-mail using your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
If you have a semi-dedicated server account from our company, you'll be able to secure your emails by activating the SPF protection service for any domain hosted in the account with just a couple of mouse-clicks. This can be done in the Emails section of the Hepsia Control Panel which is included with the semi-dedicated accounts and even if you have no previous practical experience with such issues, you won't have any kind of trouble to enable the security. The only things that you will need to do is to find a domain from a drop-down menu and after that type in the mail server hostname and IPv4 or IPv6 address. As soon as the new record propagates, messages from your e-mail addresses will be mailed worldwide only if they are sent from that specific server. If your email addresses are taken care of by us and not by a third-party supplier, you'll also be able to take advantage of an option for email messages to be mailed only when the domain has our MX records and the aforementioned would be the safest option.
