Get Started in the Lab Environment
Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!
-
Challenge
Configure and Verify Sender Policy Framework (SPF)
To start the lab, you will create a DNS entry in the globomantics.co domain that details the permitted senders for the domain. You will then verify that these entries are configured correctly.
-
Challenge
Configure and Verify DomainKeys Identified Mail (DKIM)
Next, you will configure DomainKeys Identified Mail to ensure that messages have not been modified while in transit across the internet.
-
Challenge
Configure and Verify DMARC
For the last challenge, you will configure the correct DNS record for DMARC (Domain-based Message Authentication, Reporting, and Conformance). This will allow you as the mail administrator to receive reports from receiving domains on the state of mail purporting to come from your domain.
