Sender Policy Framework, or SPF, is a verification system, that is used to stop the so-called e-mail spoofing where an email message can be sent from one email, but to seem as being sent from a different one, often with the idea to fraud the recipient for some reason. If SPF protection is activated for a domain, an exclusive record is created for it in the Domain Name System and all DNS servers worldwide have it. The record includes all of the email servers that are allowed to send authentic messages from an e-mail address under the domain. When an email is sent, the very first DNS server it goes to verifies the SPF record and when its sending server is authorized, the message is sent to the targeted destination. In case, however, the sending server is not present in the SPF record for the given domain, the e-mail message will not be forwarded and it'll be discarded. When you use this solution, it will prevent third parties from sending spam e-mails which look as if they have been sent by you.
SPF Protection in Hosting
If you host your domain names in a hosting account on our end and we handle the e-mail addresses for them, you are able to enable SPF protection for all of them with several clicks in your Hepsia Control Panel. The service is accessible in a separate section where you'll be able to view which domains are already secured. For those that aren't, you can enable the SPF protection solution and set up various things during the process - the hostnames of the mail servers that are permitted to send messages from your addresses, the IPv4 and IPv6 addresses of the servers, as well as to set a rule that messages can be sent only if your domains include our MX records. The last mentioned choice is the most secure one, but you can use it if we manage the email addresses for your domain names and you're not using another email supplier. The newly created records will be activated within a day and nobody will be able to fake the FROM field in an email by using your email addresses.
SPF Protection in Semi-dedicated Servers
The SPF protection function is provided with all of the semi-dedicated servers, so if you host your domains in an account on our cloud website hosting platform, you'll be able to use this particular service easily for all your domain names. The Hepsia Control Panel, which comes with the semi-dedicated accounts, has a rather easy to use interface, which means that you don't need to be proficient in the use of computers to secure your e-mails. You will simply have to type the hostname and the IP address of each mail server that you'd like to be certified to send out e-mails from your addresses and immediately after that the updated record will be activated for the domain name that you've selected. As an additional option, we will also allow you to control your outgoing email messages and secure your mailboxes even further by permitting emails to be sent only if the domain in question contains our MX records i.e. the emails for the domain should be managed on our end and not by some other supplier. Thus you will have even better control and there will not be any chance for any person to fake your e-mail addresses for malicious purposes.
