Kadem'is mail server is a computer system that sends and receives emails. In many cases, web servers and mail servers are combined in a single machine.
Kademi uses SPF and DKIM permissions and authorizations so emails are sent and received correctly. 

SPF - Sender Policy Framework

This a simple email validation system designed to detect email imitation by providing a mechanism to allow receiving mail exchangers to check that incoming mails from a domain come from a host authorized by that domain's administrators.

DKIM - Domain Keys Identified Mail

This is an email authentication method designed to detect email imitation. It allows the receiver to check that an email claimed to have come from a specific domain was indeed authorized by the owner of that domain.

Checking if your SPF and DKIM settings are loaded into your domain

Go to website manager, select Domains

Underneath DNS settings, click on the domain name

Click on the domain to go to the setting

If you see a value in the SPF and DKIM row, then there has been an authentification success.

SPF

mydomain.com. 300 IN TXT "v=spf1 include:_spf.kademi.us ~all"

To break this down so you understand what each column stands for, you have - Type, Value, and TTL

  • mydomain.com - please enter your domain name here

  • Value - "v=spf1 include:_spf.kademi.us ~all" - this is Kademi's code to verify your the mail domain, It has to have "v=spf1 include:_spf.kademi.us - you can add extensions before the  "~all" to add extra permissions and features if required

  • 300 is your TTL - Time to live is a mechanism that limits the lifespan or lifetime of data in a computer or network. TTL may be implemented as a counter or timestamp attached to or embedded in the data. Once the prescribed event count or timespan has elapsed, data is discarded.

DKIM

This is the same process as SPF but the value is not editable, it's a specific code which is static.
