Sender Policy Framework, or SPF, is a validation system, which is designed to prevent the so-called e-mail spoofing where an e-mail message can be sent from one email, but to seem as being sent from another, typically with the objective to fraud the recipient in some way. When SPF protection is activated for a domain, a unique record is created for it in the Domain Name System and all DNS servers worldwide have it. The record includes all mail servers that are permitted to send legitimate messages from an address part of the domain. When an e-mail is sent, the first DNS server it encounters verifies the SPF record and when its sending server is authorized, the message is forwarded to the target receiver. If, however, the sending server is not present in the SPF record for the specified domain, the email message will not be sent and it'll be removed. If you employ this solution, it'll stop third parties from sending spam that appear to have been sent by you.
SPF Protection in Shared Hosting
When you host your domains in a shared hosting account with us and we handle the emails for them, you are able to activate SPF protection for all of them with several clicks inside your Hepsia Control Panel. The service is available in its own section where you are able to view which domains are currently protected. For the ones that aren't, you'll be able to enable 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 e-mails, the IPv4 and IPv6 addresses of these servers, and even to set a rule that emails can be sent only if your domains have our MX records. The last solution is the most secure one, and it can be used in the event that we handle the emails for your domain names and you're not using some other e-mail service provider. The newly created records will propagate within one day and nobody will be able to fake the FROM field in an e-mail using your email addresses.
SPF Protection in Semi-dedicated Servers
When you have a semi-dedicated server account from our company, you'll be able to protect your email addresses by enabling the SPF security service for every domain name hosted in your account with just a couple of mouse-clicks. This is done from the Emails section of the Hepsia Control Panel which is included with the semi-dedicated accounts and even in case you have no previous experience with such issues, you won't have any kind of difficulties to activate the protection. The only things that you'll need to do will be to pick a domain from a drop-down list and then type the mail server hostname and IPv4 or IPv6 address. As soon as the new record propagates, messages from your emails will be delivered worldwide only if they're sent from that particular server. In case your e-mail addresses are managed by our company and not by a third-party provider, you will also be able to activate an option for e-mail messages to be mailed only if the domain features our MX records and this would be the safest option.
