The auto-reply feature in Plesk automatically sends a response to anyone who emails you. This is useful when you are out of the office, on holiday, or otherwise unavailable. You can set a start and end date so the auto-reply stops automatically.

### Setting Up an Auto-Reply

1. Log in to **Plesk**.
2. Go to **Mail**.
3. Click the email address you want to configure.
4. Go to the **Auto-Reply** tab.
5. Select **Switch on auto-reply**.
6. Fill in the auto-reply settings:
   - **Auto-reply message subject:** Enter a subject line (e.g., "Out of Office: Returning 15 April").
   - **Message format:** Choose **Plain text** (recommended for compatibility) or **HTML**.
   - **Message text:** Write your auto-reply message. Include:
     - The dates you are away.
     - When you expect to return.
     - An alternative contact person (if applicable).
   - **Forward to:** Optionally forward incoming messages to another email address while the auto-reply is active.
   - **Send an automatic response to a unique email address no more than:** Set how many times per day the auto-reply is sent to the same sender (default: 1). This prevents spamming frequent senders.
   - **Switch off auto-reply on:** Set an end date for the auto-reply to stop automatically.
7. Click **OK**.

### Disabling the Auto-Reply

1. Go to **Mail** → click the email address → **Auto-Reply** tab.
2. Clear **Switch on auto-reply**.
3. Click **OK**.

Alternatively, if you set an end date, the auto-reply will disable itself automatically.

### Important Notes

- The auto-reply is sent **per sender per day** by default — a sender who emails you multiple times in one day will only receive one auto-reply.
- Always set an **end date** if you know when you will return. This prevents the auto-reply from running indefinitely.
- Do not set up both a Plesk auto-reply and a Roundcube vacation message for the same email address — this will cause duplicate responses.

### Troubleshooting

**Auto-reply is not sending:**

- Verify the auto-reply toggle is switched on and you clicked **OK**.
- Check that the end date has not already passed.

**Sender receives multiple auto-replies:**

- Check the "no more than X times per day" setting — it may be set too high.
