Preface
Introduction
It may be required to provide SSL connections to the mail server for more than one virtual host. This is problematic, as TLS/SNI is not yet widely deployed. This documents one way to implement multiple server names with SSL for POP, IMAP, SMTP and Webmail services, and assumes you're familiar with SSL certificates and basic zimbra installation.
Starting Point
The starting point for this configuration is a standard zimbra installation with proxy enabled. While this is intended for a scaleable, multiserver, installation, it can be used in a single server instance as well. Doing so simplifies configuration in that you only need to configure nginx and postfix to cover all the services.
