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 is sent from one email, but to seem as being sent from another, usually with the purpose to fraud the recipient for some reason. When SPF protection is enabled for a domain, a specific record is made for it in the Domain Name System and all DNS servers around the world have it. The record contains all the mail servers that are allowed to send authentic messages from an address part of the domain. When an e-mail is sent, the first DNS server it goes to checks the SPF record and in case the sending server is permitted, the message is sent to the target 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 removed. If you use this solution, it will stop third parties from sending spam e-mails which look as if they have been sent by you.
SPF Protection in Website Hosting
When you host your domain names in a website hosting account on our end and we manage the emails for them, you are able to activate SPF protection for all of them with a few clicks in your Hepsia Control Panel. This service is accessible in its own section where you're able to see which domains are already protected. For those that aren't, you will be able to activate the SPF protection service and set up numerous things during this process - the hostnames of the mail servers that are allowed to send messages from your e-mails, the IPv4 and IPv6 addresses of the servers, as well as to set a rule that emails can be sent only if your domains include our MX records. The last mentioned option is the most secure one, but you can use it if we take care of the email addresses for your domain names and you are not using another e-mail supplier. The new records will be activated within 24 hours and nobody will be able to forge the FROM field in an email using your email addresses.
SPF Protection in Semi-dedicated Hosting
If you have a semi-dedicated server account from our company, you will be able to secure your emails by enabling the SPF security service for every domain hosted in your account with just a couple of mouse-clicks. You can do this through the Emails section of the Hepsia Control Panel that is included with the semi-dedicated accounts and even in case you have no previous practical experience with these kinds of issues, you will not have any problems to activate the security. The only things that you'll need to do is to select a domain name from a drop-down list and after that type the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your email addresses will be mailed worldwide only if they are sent from that specific server. In case your emails are handled by us and not by a third-party provider, you can also use an option for email messages to be sent only when the domain name features our MX records and the latter would be the safest option. Should you have any kind of questions related to thisfunction, you'll be able to contact our support team 24/7.
