Sender Policy Framework, or SPF, is a verification system, that is designed to prevent the so-called email spoofing where an e-mail message is sent from one e-mail address, but to look as being sent from a different, ordinarily with the objective to scam the recipient in some way. When SPF protection is enabled for a domain name, a special record is made for it in the Domain Name System and all of the DNS servers worldwide have it. The record includes all of the mail servers that are permitted to send authentic messages from an e-mail address within the domain. When a message is sent, the very first DNS server it goes to verifies the SPF record and if the sending server is permitted, the message is forwarded to the targeted receiver. In case, however, the sending server is not included in the SPF record for the given domain, the e-mail message won't be sent and it'll be removed. Whenever you use this service, it'll prevent third parties from sending spam messages that seem to have been sent by you.
SPF Protection in Cloud Hosting
When you host your domain names 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 few clicks in your Hepsia Control Panel. The service can be found in its own section where you're able to see which domains are already secured. For those that aren't, you can activate the SPF protection option and configure numerous things during the process - the hostnames of the mail servers that are permitted to send messages from your mailboxes, the IPv4 and IPv6 addresses of the servers, and to set a rule that messages can be sent only when your domain names use our MX records. The last option is the most secure one, but you can use it in the event that we manage the emails for your domains and you are not using a different e-mail 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 host your domains in a semi-dedicated server account from us, you'll be able to benefit from the SPF protection feature as part of the regular group of services that you will get with this type of hosting. Enabling the protection requires only a couple of easy steps inside the Hepsia Control Panel, therefore even if you've never used such a function before, you won't have any issues. Through a really time and effort saving interface, you'll simply need to insert the information of the mail server that will be certified to send out messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the newly generated record propagates, nobody will be able to fake any e-mail address for that particular domain name and send out e-mail messages from a server different from the one you have entered. This does not specifically have to be our mail server, however if we take care of your e-mails, you'll be able to allow an extra level of security by selecting an option that e-mail messages can be send out from addresses @your-domain.com only in case the domain uses our MX records. Our technical support team will be able to help you 24/7 in case you have any kind of questions about this service.
