# Email Source Code Analysis

When troubleshooting delivery or display issues, the [[universitatsrechenzentrum-urz]] may request the **source code** (raw text) of an email. This includes the **Internet Headers**, which contain routing information and timestamps.

## Extraction Methods by Client

### Groupware
- Right-click the email in the email module and select **Quelltext anzeigen** (Show source).

### Mozilla Thunderbird
- Open the email and go to **Ansicht** (View) $\rightarrow$ **Quelltext anzeigen** (Show source).
- Shortcut: `Ctrl + U`.

### Microsoft Outlook
Outlook separates the source into two parts:
1. **Internet Headers**: Found in the message properties.
    - Double-click the message $\rightarrow$ **Datei** (File) $\rightarrow$ **Informationen** (Information) $\rightarrow$ **Eigenschaften** (Properties).
    - Alternatively, use the arrow icon ($\searrow$) next to the "Categories" group in the Message ribbon.
2. **Message Body Source**: Right-click inside the email message and select **Quelle anzeigen** (Show source).
