+### Using Caddy certificate for TLS
+
+#### Setup automatic copying from Caddy to Postal
+
+To remove the need of the manual maintenance task to copy the certificate from Caddy to Postal, we can automate this. The original discussion and author can be found [here](https://github.com/orgs/postalserver/discussions/2673).
+
+##### Install inotify-tools
+
+Install the toolset which provides `inotifywait`, used to monitor certificate changes.
+
+```bash
+sudo apt-get update
+sudo apt-get install inotify-tools
+```
+
+##### Create Monitoring Script
+
+Create a script named `monitor_certs.sh`:
+
+```bash
+nano /opt/postal/monitor_certs.sh
+```
+
+Add following code to the script file:
+
+```bash
+#!/bin/bash
+
+CERT_DIR="/opt/postal/caddy-data/caddy/certificates/acme-v02.api.letsencrypt.org-directory/YOURDOMAIN/"
+CERT_FILE="${CERT_DIR}YOURDOMAIN.crt"
+KEY_FILE="${CERT_DIR}YOURDOMAIN.key"
+
+while true; do
+    inotifywait -e modify "$CERT_FILE" "$KEY_FILE"
+
+    # Copy the certificates to Postal's configuration directory
+    cp "$CERT_FILE" /opt/postal/config/smtp.cert
+    cp "$KEY_FILE" /opt/postal/config/smtp.key
+
+    # Adjust permissions to ensure Postal can read the certificates
+    chmod o+r /opt/postal/config/smtp.*
+
+    # Restart Postal to use the new certificates
+    postal restart
+done
+```
+
+Make the script executable:
+```bash
+chmod +x /opt/postal/monitor_certs.sh
+```
+
+##### Create a systemd Service
+
+Make a systemd service file:
+
+```bash
+sudo nano /etc/systemd/system/monitor_certs.service
+```
+
+Insert the following content:
+
+```yaml
+[Unit]
+Description=Monitor Caddy Certificates for Postal
+
+[Service]
+ExecStart=/opt/postal/monitor_certs.sh
+Restart=always
+User=your_username 
+Group=your_groupname
+
+[Install]
+WantedBy=multi-user.target
+```
+
+##### Activate the Service
+
+Reload the systemd daemons:
+
+```bash
+sudo systemctl daemon-reload
+```
+
+Enable and start the service:
+
+```bash
+sudo systemctl enable monitor_certs.service
+sudo systemctl start monitor_certs.service
+```
+
+##### Initial Manual Certificate Copy
+
+Before the monitoring script takes over, you should manually copy the certificates for the first time:
+
+```bash
+cp /opt/postal/caddy-data/caddy/certificates/acme-v02.api.letsencrypt.org-directory/YOURDOMAIN/YOURDOMAIN.crt /opt/postal/config/smtp.cert
+cp /opt/postal/caddy-data/caddy/certificates/acme-v02.api.letsencrypt.org-directory/YOURDOMAIN/YOURDOMAIN.key /opt/postal/config/smtp.key
+chmod o+r /opt/postal/config/smtp.*
+```
+
 ## Configuration
 
 Once you have a key and certificate you will need to enable TLS in the configuration file (`/opt/postal/config/postal.yml`). Additional options are available too.
