Sender Policy Framework, or SPF, is a validation system, that is employed to stop the so-called e-mail spoofing where an e-mail message can be sent from one address, but to look as being sent from another, usually with the idea to fraud the recipient in some way. If SPF protection is activated for a domain, a special record is made for it in the Domain Name System and all DNS servers globally receive it. The record features all of the mail servers that are permitted to send authentic messages from an e-mail address under the domain. When a message is sent, the first DNS server it goes to verifies the SPF record and if its sending server is authorized, the message is sent to the targeted destination. In case, 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 discarded. Whenever you use this solution, it will prevent third parties from sending spam messages which appear to have been sent by you.

SPF Protection in Shared Hosting

If you host your domains in a shared hosting account on our end and we manage the e-mail addresses for them, you'll be able to activate SPF protection for them with a few clicks inside your Hepsia Control Panel. This service is accessible in a separate section where you'll be able to view which domain names are already secured. For the ones that aren't, you'll be able to enable the SPF protection option and configure various things at the same time - the hostnames of the mail servers that are allowed to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of the 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 mentioned choice is the most secure one, but you can use it when we take care of the e-mails for your domain names and do not use some other email provider. The new records will be activated within 24 hours and nobody will be able to fake the FROM field in an e-mail using your addresses.

SPF Protection in Semi-dedicated Hosting

The SPF protection attribute is featured with all the Linux semi-dedicated hosting, so in case you host your domains in an account on our cloud hosting platform, you're able to activate this service easily for all of your domains. The Hepsia Control Panel, which is provided with the semi-dedicated accounts, features a quite easy to work with interface, so you do not have to be proficient in the use of computers to secure your e-mail addresses. You will only have to type the hostname and the IP of each mail server that you'd like to be authorized to send out emails from your addresses and shortly after that the updated record will be activated for the domain name that you've picked. As a further option, we will also allow you to limit the outgoing emails and protect your mailboxes further by permitting email messages to be sent only if the domain in question has our MX records i.e. the emails for the domain name have to be taken care of on our end and not by a different company. Thus you'll enjoy even better control and there won't be any chances for anyone to counterfeit your email addresses for harmful intentions.
