When you finally open the correct config file, here is what the "linked" structure looks like:
However, here are the most useful official links:
Don’t have one config to rule them all.
Securing PowerMTA and its monitoring interface is critical for any production deployment. powermta config file link
Another useful command:
For production environments, always combine configuration linking with version control (e.g., Git) and automated validation in your deployment pipeline.
An optimized configuration must also protect your mail server from unauthorized relay abuse and ensure message integrity. Enforcing TLS Encryption When you finally open the correct config file,

Tips for Optimizing Your Config
Instead of writing everything in one place, add links to external files inside /etc/pmta/config : An optimized configuration must also protect your mail

This directive your PMTA configuration to the actual cryptographic key file. Without this link, DKIM signing fails.
At its core, you only need a few key directives to define the server's behavior:
# /etc/pmta/config (main file)
PowerMTA imposes a limit on nested includes (links to files that include other files). You cannot exceed . Exceeding this will yield a config: too many include levels error.
