I have been looking for quite a while now for an app that can take a directory and give a list of all the e-mails beneath it. By this I mean, I use qmail with vpopmail and would like to be able to view all the users mail at once. Structured exactly as it would be in a file manager (or along these lines) except using the subject line as whats displayed instead of the actual filename on the disk. It would be also handy to be able to read the message and move mail one user to another. I would have thought this would be a common requirement for people running mail servers but I can't find anything that will do what I require. I would preferably like a GUI environment (mainly for my boss, who's not very familiar with Linux) but a console app would be just as handy.
Any pointing in the right direction would be very much appreciated.
