Import the powermta.template.xml into your Zabbix server and assign it to the host. If you want, I can: Show you specific commands to check queues in the console. Explain how to set up alerts for blocked IPs. Provide a sample JSON configuration for monitoring tools. Let me know which of these would help you most! Why typo domains can cause severe email delivery issues

PowerMTA acts as the final gateway between an organization and the receiving Internet Service Providers (ISPs). Consequently, monitoring PowerMTA is not merely about server uptime; it is about visibility into the handshake between the sender and the receiver.
