Sender Policy Framework, or SPF, is a verification system, that is employed to stop the so-called e-mail spoofing where an e-mail message is sent from one address, but to seem as being sent from a different one, usually with the purpose to fraud the recipient for some reason. When SPF protection is enabled for a domain, an exclusive record is made for it in the Domain Name System and all the DNS servers worldwide get it. The record features all the e-mail servers that are permitted to send legitimate messages from an email address part of the domain. When an e-mail is sent, the first DNS server it goes to verifies the SPF record and if its sending server is permitted, the message is forwarded to the target receiver. When, however, the sending server is not contained in the SPF record for the specified domain, the message will not be submitted and it will be removed. If you use this service, it will prevent third parties from sending spam e-mails that appear to have been sent by you.
SPF Protection in Hosting
If you host your domains in a hosting account on our end and we handle the emails for them, you'll be able to enable SPF protection for any of them with a couple of clicks inside your Hepsia Control Panel. The service is accessible in a section of its own where you will be able to view which domain names are currently secured. For those that aren't, you'll be able to activate the SPF protection service and configure a lot of things at the same time - the hostnames of the mail servers that are allowed to send messages from your mailboxes, the IPv4 and IPv6 addresses of these servers, as well as to create a rule that email messages can be sent only if your domain names use our MX records. The last option 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 a different email provider. The newly created records will be activated within a day and nobody will be able to fake 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 with us, you will be able to employ the SPF protection feature as a part of the standard group of services that you'll get with this type of hosting. Enabling the protection involves only several simple steps within the Hepsia Control Panel, therefore even when you've never used this type of feature before, you will not have any problems. Through a really user-friendly interface, you'll just have to insert the information of the mail server that will be permitted to send out messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the newly generated record propagates, nobody will be able to fake any e-mail for that particular domain and send out e-mails from a server different from the one you've typed in. This does not specifically have to be our mail server, but when we take care of your emails, you're able to allow one more level of security by picking an option that emails can be send out from addresses @your-domain.com only if the domain uses our MX records. Our tech support staff will be able to assist you 24/7 in case you have any kind of questions about this service.
