# Mailing List Server

The **Mailing List Server** is a centralized service provided by the [[universitatsrechenzentrum-urz]] to facilitate communication with large groups of recipients.

## Functional Types
1. **Discussion Lists (Diskussionslisten)**: Designed for interactive communication. Subscribers can read and post messages to a shared topic or project group.
2. **Distribution Lists (Verteilerlisten)**: Designed for one-way or automated broadcasting. Members are often added automatically based on university enrollment or organizational roles (e.g., StuPa, AStA).

## Technical Constraints and Rules
- **Minimum Size**: A formal mailing list is only created if the group consists of **at least 10 members**.
- **Small Group Alternative**: For groups smaller than 10, the URZ recommends using functional accounts configured with **Sieve rules** for distribution.
- **Addressing**: Emails are sent to the format `LISTENNAME@listen.uni-greifswald.de`.

## Naming Conventions
When requesting a list via [[ums]], the following naming structures are mandatory:
- **Working Groups/Projects**: `einrichtungsname_arbeitsgruppe/projekt`
- **Student Councils (FSR)**: `fsr_fachschaftsname`
- **Students by Subject**: `stud_studienfach`

## Moderation
The server supports moderation, where a designated administrator must review and approve posts before they are distributed to the list members. This is managed via the [[sympa]] web interface.
