Sender Policy Framework, or SPF, is a verification system, which is intended to prevent the so-called email spoofing where an email message is sent from one address, but to look as being sent from a different, typically with the objective to fraud the recipient someway. If SPF protection is activated for a domain name, a specific record is generated for it in the Domain Name System and all the DNS servers globally have it. The record contains all email servers that are permitted to send valid messages from an address under the domain. When an email is sent, the very first DNS server it goes to checks the SPF record and when the sending server is authorized, the message is sent to the targeted receiver. If, however, the sending server is not present in the SPF record for the given domain, the e-mail message won't be submitted and it'll be discarded. Whenever you employ this service, it will prevent third parties from sending spam emails which look as if they have been sent from you.
SPF Protection in Shared Web Hosting
If you host your domains in a shared web 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. This service is accessible in its own section where you're able to see which domain names are already secured. For those that are not, you can activate the SPF protection option and set up a lot of things during the process - the hostnames of the mail servers that are permitted to send messages from your email addresses, the IPv4 and IPv6 addresses of the servers, as well as to set a rule that email messages can be sent only if your domain names include our MX records. The last choice is the most secure one, but it can be used if we take care of the email addresses for your domain names and you are not using a different email supplier. The newly generated records will be activated within a 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 Servers
When you host your domain names in a semi-dedicated server account from us, you can employ the SPF protection feature as a part of the conventional group of services that you'll get with this type of website hosting. Starting the protection will require just a few easy steps inside the Hepsia Control Panel, so even when you've never employed this kind of function before, you will not have any kind of troubles. Through a very easy to work with interface, you will only need to input the details of the mail server which will be certified to send messages from your email addresses - its hostname ( and IP address (IPv4 or IPv6). Once the recently made record propagates, no one will be able to counterfeit any email for that particular domain and send e-mail messages from a server different from the one you've entered. This doesn't necessarily have to be our mail server, still if we manage your emails, you will be able to activate one more level of protection by selecting an option that e-mail messages can be send from addresses only if the domain employs our MX records. Our tech support team can help you 24/7 in case you have any questions regarding this service.
