CommuniGate Pro is a fully featured Internet mail server that uses a built-in HTTP server. It can be configured remotely using any Web browser. But the great part is that the server does not conflict with any other Web Server running on your computer, which means that Apache will still work. As an alternative to the standard Web Administrator interface, the server also provides a Command Line Interface for server administration. The CLI can be used to manage the server via scripts and other programs that issue commands to the server.
System logs are also a great option.
The logs in CommuniGate Pro include a time stamp, a log level and a tag identifying the component that created the record. The CommuniGate Pro Server can also work on a site that only has a dial-up Internet connection, allowing LAN users to access their mail and to submit messages without connecting to the Internet. This allows the System Administrator to specify when the system will go online and send and receive mail. Users can connect to the CommuniGate Pro Server with any Web browser, so whatever operating system your users have will not matter. Users can also manage their accounts, browse the list of mailboxes in their account, search mailboxes for data, move messages between mailboxes, and redirect messages to other accounts.
