Sample Powermta Configuration File Hot

The warmup block inside domain directives is a game-changer. Instead of manually raising limits, PowerMTA automatically increases max-msg-rate over 7-10 days. This prevents ISPs from throttling you as a "sudden burst" sender.

Add this to your global section to let PowerMTA auto-adjust based on ISP responses: sample powermta configuration file hot
