Every so often, I like to clean out my PM mailboxes and download the messages to my PC.

The trouble is that none of the formats are particularly readable (at least, by me), especially when there are lots of nested quotes. I know that there's a Windows program for viewing vBulletin PMs, which displays them the same as they look when logged in, but I've seen no mention of Linux anywhere.

Does anyone know anything about this? Even sed/awk scripting so that the messages could be imported into an email client would be acceptable.
