Single server

A Zimbra installation with one server runs MSH Zimbra Rules on that host: the web admin, the node and the milter run next to Zimbra and its MTA. See Deployment layouts for how they connect.

Install in this order:

1. Java - install Java 21.
2. Installation - unpack the package to /opt/msh-zr, start the web admin, node and milter services and log in.
3. Milter configuration - register the milter in the Zimbra MTA with zmprov.
4. Zimlet configuration - install the Zimbra extension and the Change User Info zimlets, so users can change their own attributes used in signatures.
