hMailLive is an open source addition to the excellent hMailServer.
This addition will provide you with stats and general information about your email server. One day I hope to enhance this series of scripts, but unfortunately I no longer have the time. For help please use the entry on the hMailServer forum, although do not abuse as these scripts are NOT SUPPORTED.
Installation for anyone with any Perl / IIS or Apache / MySQL experiance shouldn't be too taxing.
You can edit this script as you see fit as long as you distribute the modified code. Ideally by emailing it to me and I will add a download location here for the revised scripts.
