In this chapter, we saw, step-by-step, how to install Zimbra in a multiserver environment. We started by describing the prerequisites, then preparing the environment for multiserver installation; next, we ran through all the installation steps for each server until we finally ran Zimbra and tested it.

Now, after seeing how to install Zimbra in both single and multiserver environments, it is time to start looking for something to protect our installation, which is how we can improve security inside Zimbra, especially antivirus/antispam tools. That is the subject of the next chapter.
