Sender Policy Framework, or SPF, is a verification system, that is intended to prevent the so-called e-mail spoofing where an e-mail message can be sent from one e-mail, but to seem as being sent from a different one, typically with the purpose to scam the recipient someway. When SPF protection is enabled for a domain name, a special record is made for it in the Domain Name System and all the DNS servers globally receive it. The record features all of the e-mail servers that are permitted to send valid messages from an email address under the domain. When an e-mail is sent, the first DNS server it goes to verifies the SPF record and when its sending server is permitted, 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 email message will not be sent and it will be discarded. If you employ this solution, it'll prevent third parties from sending spam emails which appear to have been sent by you.
SPF Protection in Cloud Hosting
When you host your domains in a cloud hosting
account on our end and we handle the emails for them, you'll be able to activate SPF protection for any of them with several clicks inside your Hepsia Control Panel. The service is available in a separate section where you'll be able to view which domain names are already secured. For the ones that aren't, you can enable the SPF protection option and configure various things in the process - the hostnames of the mail servers that are allowed to send messages from your e-mails, the IPv4 and IPv6 addresses of these servers, and to set a rule that emails can be sent only if your domain names have our MX records. The last solution is the most secure one, but it can be used if we take care of the e-mail addresses for your domain names and do not use some other e-mail service provider. The new records will be activated within one day and nobody will be able to forge the FROM field in an email by using your email addresses.
SPF Protection in Semi-dedicated Servers
The SPF protection feature is provided with all of the semi-dedicated servers
, so in case you host your domain names in an account on our cloud web hosting platform, you will be able to activate the service without difficulty for any of your domain names. The Hepsia Control Panel, which is provided with the semi-dedicated accounts, offers a very easy to work with interface, so you don't need to be tech-savvy in order to protected your e-mails. You'll only need to type the hostname and the IP of each mail server that you would like to be allowed to send out e-mails from your addresses and shortly after that the updated record will be active for the domain that you've chosen. As a further option, we'll also allow you to limit the outgoing email messages and protect your mailboxes further by allowing emails to be sent only when the domain name involved has our MX records i.e. the emails for the domain need to be handled here and not by a different provider. In this way you'll get even superior control and there will not be a chance for anybody to forge your emails for malicious intentions.
