vmail-sql is a complete virtual domains email setup, including sample Exim configuration sections, reference to tpop3d which will authenticate access to mailspools against the virtual user database, a set of admin-level scripts for administrating domains, and a Web-based control panel. Rather than storing the virtual domains setup in flat text files, it uses a MySQL database, allowing flexible administration strategies without concurrency hassles. It is designed for use in environments where several virtual domains are operated from a single machine/IP address.
