MHonarc (Score 1)

I've been looking for a solution to this same problem for a long time. For now, I still have all my email from the last 10 years stored in my MS Entourage database. Scary. What I would like to do is convert them all to HTML and/or plain text so that it's searchable, and won't need a special app to view them. Who knows what formats will still be around in 10, 20, 30+ years? But I suspect HTML and plain text will survive.

What I don't like about the mbox archiving technique is that you have to import the mbox into an email app to read it. To me, that sounds like a chore because I'd want to keep those messages separate from my current email box, and then there's processing time it takes to import it, etc.

It seems to me that an ideal situation would be that the file system can search it (i.e. Spotlight in Mac OS X 10.4 Tiger) or use a web browser.

There is a solution for archiving emails to HTML: MHonarc. I've played with it in the past and it does its job fairly well. What annoys me about the script is how difficult it is to customize the output, especially if you want it to validate and use CSS.

There's nothing else out there that I could find to my satisfaction. Maybe some resourceful developers want to embark on a new OSS project??? :)
