Hep Message Server is software that transfers messages between different messaging systems. Eventually, it should transparently route messages between email, weblogs, and instant messaging. Currently Hep does one thing: fetches news feeds from Web sites and lets you view them in your email client.
XMail Queue Manager gives you control over an XMail Server's multi-level nested mail queue. You can use it to track messages in their different states (sending, resending, and frozen). Statistics tell you about the number of spooled messages. You can sort entries by any column header field, and can start and stop the server directly. The cross platform remote control feature allows you to manage queues on remote servers without a GUI.
