+
+## Overview
+
+This collector retrieves statistics about the Postfix mail queue using the [postqueue](https://www.postfix.org/postqueue.1.html) command-line tool.
+
+
+It periodically executes the `postqueue -p` command. The collection interval is set to 10 seconds by default, but this can be configurable.
+
+
+This collector is supported on all platforms.
+
+This collector only supports collecting metrics from a single instance of this integration.
+
+Postfix has internal access controls for the mail queue. By default, all users can view the queue. If your system has stricter controls, grant the `netdata` user access by adding it to `authorized_mailq_users` in the `/etc/postfix/main.cf `file. For more details, refer to the `authorized_mailq_users` setting in the [Postfix documentation](https://www.postfix.org/postconf.5.html).
+
+
+### Default Behavior
+
+#### Auto-Detection
+
+The collector executes  `postqueue -p` to get Postfix queue statistics.
+
+#### Limits
+
+The default configuration for this integration does not impose any limits on data collection.
+
+#### Performance Impact
+
+The default configuration for this integration is not expected to impose a significant performance impact on the system.
+
+
+## Metrics
+
+Metrics grouped by *scope*.
+
+The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
+
+
+
+### Per Postfix instance
+
+These metrics refer to the entire monitored application.
+
+
+This scope has no labels.
+
+Metrics:
+
+| Metric | Dimensions | Unit |
+|:------|:----------|:----|
+| postfix.qemails | emails | emails |
+| postfix.qsize | size | KiB |
+
+
+
+## Alerts
+
+There are no alerts configured by default for this integration.
+
+
+## Setup
+
+### Prerequisites
+
+No action required.
+
+### Configuration
+
+#### File
+
+There is no configuration file.
+#### Options
+
+The following options can be defined globally: update_every.
+
+
+<details open><summary>Config options</summary>
+
+| Name | Description | Default | Required |
+|:----|:-----------|:-------|:--------:|
+| update_every | Data collection frequency. | 10 | no |
+| binary_path | Path to the `postqueue` binary. If an absolute path is provided, the collector will use it directly; otherwise, it will search for the binary in directories specified in the PATH environment variable. | /usr/sbin/postqueue | yes |
+| timeout | Timeout for executing the binary, specified in seconds. | 2 | no |
+
+</details>
+
+#### Examples
+There are no configuration examples.
+
+
+
+## Troubleshooting
+
+### Debug Mode
+
+To troubleshoot issues with the `postfix` collector, run the `go.d.plugin` with the debug option enabled. The output
+should give you clues as to why the collector isn't working.
+
+- Navigate to the `plugins.d` directory, usually at `/usr/libexec/netdata/plugins.d/`. If that's not the case on
+  your system, open `netdata.conf` and look for the `plugins` setting under `[directories]`.
+
+  ```bash
+  cd /usr/libexec/netdata/plugins.d/
+  ```
+
+- Switch to the `netdata` user.
+
+  ```bash
+  sudo -u netdata -s
+  ```
+
+- Run the `go.d.plugin` to debug the collector:
+
+  ```bash
+  ./go.d.plugin -d -m postfix
+  ```
+
+### Getting Logs
+
+If you're encountering problems with the `postfix` collector, follow these steps to retrieve logs and identify potential issues:
+
+- **Run the command** specific to your system (systemd, non-systemd, or Docker container).
+- **Examine the output** for any warnings or error messages that might indicate issues.  These messages should provide clues about the root cause of the problem.
+
+#### System with systemd
+
+Use the following command to view logs generated since the last Netdata service restart:
+
+```bash
+journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep postfix
+```
+
+#### System without systemd
+
+Locate the collector log file, typically at `/var/log/netdata/collector.log`, and use `grep` to filter for collector's name:
+
+```bash
+grep postfix /var/log/netdata/collector.log
+```
+
+**Note**: This method shows logs from all restarts. Focus on the **latest entries** for troubleshooting current issues.
+
+#### Docker Container
+
+If your Netdata runs in a Docker container named "netdata" (replace if different), use this command:
+
+```bash
+docker logs netdata 2>&1 | grep postfix
+```
+
+
