+            Stalwart Mail Server is a high-performance, open-source mail server solution.
+
+            ⚠️ **CRITICAL PREREQUISITES:**
+            1. Ensure ports **25, 587, 465, and 993** are NOT used by other apps on this server.
+            2. If you have Postal or Poste.io running, stop them before deploying.
+            3. Verify if your VPS provider blocks outgoing connections on Port 25.
+
+        end: |-
+            ✅ **Deployment Successful!**
+
+            Before you start using it, please follow these steps to ensure stability and correct IP detection.
+
+            **Step 1: Enable Host Networking (Recommended for Real IP detection)**
+            1. Go to **App Configs** for `$$cap_appname`.
+            2. Paste the following into the **Pre-Deploy Script** box:
+               `var preDeployFunction = function (captainAppObj, dockerUpdateObject) {var ports = dockerUpdateObject.EndpointSpec.Ports || [];ports.forEach(function (port) {port.PublishMode = "host";});return Promise.resolve(dockerUpdateObject);};`
+            3. Click **Save & Update**.
+
+            **Step 2: Enable HTTPS**
+            1. Go to **HTTP Settings**.
+            2. Enable **HTTPS** and **Force HTTPS**.
+            3. Ensure "Container Port" is set to `8080`.
+
+            **Step 3: Initial Setup & Password**
+            1. Go to **App Configs** -> **View Logs** (document icon).
+            2. Look for a line saying: `Admin password: XXXXXXXX`. Copy it.
+            3. Access your dashboard at: `https://$$cap_appname.$$cap_root_domain`
+            4. Log in with user `admin` and the password from the logs.
+
+            **Step 4: Moodle Configuration**
+            - **SMTP Host:** `$$cap_appname.$$cap_root_domain` (or your dedicated mail domain)
+            - **Port:** `587`
+            - **Security:** `STARTTLS`
