Key metrics to monitor

• Delivery rate: Percentage of accepted deliveries vs. attempts.
• Bounce rate / bounce types: Hard vs. soft bounces and bounce codes (4xx vs 5xx).
• Rejects: Messages refused by remote servers (often due to reputation or policy).
• Deferred rate: Temporary failures causing retries (transient issues like greylisting or throttling).
• Throughput / TPS (messages/sec): Inbound and outbound messages per second.
• Queue depth / age: Number of messages in queue and oldest message age.
• Connection concurrency: Open SMTP connections per IP/instance.
• Errors / SMTP response codes: Non-2xx responses from remote MTAs and PMTA internal errors.
• Latency / round-trip time: Time to complete SMTP transaction or to get final status.
• IP reputation / blacklist hits: Presence on RBLs, complaint rates per IP.
• Complaints (abuse/feedback loop): Spam complaints from ISPs/feedback loops per IP/campaign.
• DKIM/SPF/DMARC pass rates: Authentication success percentages.
• TLS usage rate: Percentage of deliveries using TLS.
• Resource metrics: CPU, memory, disk I/O, network bandwidth on PMTA hosts.
• Configuration drift / restart events: Unexpected config reloads or process restarts.
• License/Throughput limits: License errors or throttling imposed by PowerMTA.

Import Template: 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!
