# URZ: E-Mail einrichten - Mac E-Mail Client

This source provides detailed instructions for configuring the native Apple Mail client on macOS to work with the Universität Greifswald email system.

## Key Technical Specifications
The document specifies the following server settings for university email:

| Protocol | Server | Port | Encryption |
| :--- | :--- | :--- | :--- |
| Incoming (IMAP) | `imap.uni-greifswald.de` | 143 | STARTTLS |
| Outgoing (SMTP) | `smtp.uni-greifswald.de` | 587 | STARTTLS & Authenticated |

## Critical Requirements and Constraints
- **OS Version**: The native Mail app requires **macOS 10.12 (Sierra)** or higher to support **TLSv1.2**. Users on older versions cannot retrieve messages and are advised to use [[mozilla-thunderbird]].
- **Authentication**: Users must use their [[zentraler-nutzeraccount]] (URZ username) for authentication.
- **SMTP Port**: The macOS setup assistant often defaults to Port 25. The URZ strongly recommends manually changing this to **Port 587**.

## Configuration Workflow
The guide distinguishes between two scenarios:
1. **First-time setup**: Using the initial setup assistant upon launching the Mail app.
2. **Adding additional accounts**: Navigating via `Mail -> Settings -> Accounts` and using the `[+]` button.

To correct the SMTP settings, users must disable "Manage connection settings automatically" in the Server Settings dialog to manually enter Port 587 and enable TLS/SSL encryption with password authentication.
