Can anyone recommend a good tool for offline browsing of mbox or Maildir files? Or perhaps a filter for converting such data to HTML?
My problem is that I have enormous amounts of correspondence in old mbox or maildir data from particular periods of time, using particular mail clients, etc. In many cases, the client and even the mail accounts for this correspondence is defunct. I don't even want to keep it on my "live" machine anymore, I'd rather just write it out to a CD.
In principle, of course, I can backup the mail directories to a CD.
But how can I read them? Most mail clients are designed to work as MUAs, so you need to set up accounts and reference external servers, etc. Alternatively, I can just open an mbox file in gvim -- but this is a terrible interface and hard to read, let alone search.
I'd like to find a "client" which is just a "browser" of mbox/maildir files. Then I could just set it up as a "helper app" in Mozilla, or else use it independently.
I can imagine writing such a tool, but I'd rather not reinvent the wheel. Surely somebody has done this before?
