## Common questions

### Is the git repository version suitable for replacing a production Roundcube installation?

No, the repository snapshot is not a stable version and replacing an existing installation with it is not recommended. If you use it, using a separate database is highly recommended.

### What do I need to install before configuring LDAP address books on a Debian-based system?

Install the listed LDAP server packages first. Without them, Roundcube cannot look up contacts in that directory.

### Do Roundcube plugins and skins that call the core have to be treated as GPL modifications?

Roundcube is GPL with an exception: plugins and skins that merely make function calls and include Roundcube by reference are not considered modifications.

### Does Roundcube impose a fixed limit on users or messages?

The project’s website lists unlimited users and messages.
