Managing a PowerMTA configuration goes beyond syntax; it's about creating a reliable and scalable system. Advanced Deliverability Traffic Shaping <
After you've made your changes, you must apply them. While a full restart ( systemctl restart pmta ) works, a ( pmta reload ) is often sufficient and less disruptive for minor changes.
You can define multiple listeners to separate traffic types (e.g., inbound vs. submission).
Example:
: Specify the IP and port PowerMTA should listen on for incoming mail: smtp-listener 0.0.0.0:25 (listens on all available IPs on port 25). Virtual MTAs (VMTAs) : Define the source IPs used for sending:
Access the Web Monitor (typically on port 8080) to view real-time traffic and delivery status.
