Sender Policy Framework, or SPF, is a validation system, which is employed to stop the so-called e-mail spoofing where an e-mail message is sent from one e-mail, but to appear as being sent from another one, often with the purpose to scam the recipient in some way. If SPF protection is enabled for a domain, a specific record is generated for it in the Domain Name System and all of the DNS servers around the world receive it. The record features all the mail servers that are permitted to send authentic messages from an address within the domain. When a message is sent, the very first DNS server it encounters checks the SPF record and if the sending server is permitted, the message is forwarded to the targeted destination. If, however, the sending server doesn't exist in the SPF record for the particular domain, the e-mail message won't be sent and it will be removed. Whenever you employ this solution, it will prevent third parties from sending spam messages which look as if they have been sent by you.
SPF Protection in Shared Web Hosting
If you host your domain names in a shared web hosting account on our end and we handle the e-mails for them, you'll be able to activate SPF protection for them with a couple of clicks inside your Hepsia Control Panel. This service is accessible in its own section where you'll be able to see which domains are currently protected. For the ones which aren't, you'll be able to activate the SPF protection option and manage a variety of things in the process - the hostnames of the mail servers that are permitted to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of the servers, as well as to set a rule that messages can be sent only if your domain names use our MX records. The last mentioned solution is the most secure one, and it can be used in the event that we manage the e-mail addresses for your domain names and you are not using some other e-mail provider. The newly created records will be activated within 1 day and nobody will be able to forge the FROM field in a message by using your e-mail addresses.
SPF Protection in Semi-dedicated Hosting
If you host your domain names in a semi-dedicated server account from us, you are able to employ the SPF protection feature as part of the regular collection of services that you'll get using this type of web hosting. Starting the protection requires only a couple of easy steps in the Hepsia Control Panel, so even when you haven't used such a function before, you will not have any kind of issues. Through an exceptionally easy-to-use interface, you'll only need to insert the details of the mail server that will be certified to send messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the recently made record propagates, no one will be able to forge any e-mail address for that particular domain and send out e-mail messages from a server other than the one you've entered. This does not specifically have to be our mail server, yet in case we take care of your email messages, you are able to enable an extra level of security by picking an option that e-mails can be send out from addresses @your-domain.com only in case the domain employs our MX records. Our tech support staff can assist you 24/7 if you have any kind of questions regarding this service.
