# Groupware: Signing Emails

This source provides instructions on how to digitally sign emails using the Groupware E-Mail module at the Universität Greifswald.

## Key Instructions
- **Prerequisite**: A certificate must be successfully imported into the Groupware system before signing is possible.
- **Manual Signing**: When composing a new email, the digital signature can be enabled or disabled via the **Additional Options** button (**⋮**).
- **Automatic Signing**: The system allows for a configuration where emails are signed automatically by default.
- **Authentication**: For the first signed email sent within a specific Groupware session, the user is prompted to enter the password for their private key (the password associated with the uploaded `.p12` file).

## Support
Technical issues are handled by the [[universitatsrechenzentrum-urz]] via:
- The [[groupware]] ticket system.
- The URZ hotline (extension 1420).
