Thanks - I think most of what I'd want to keep is still accessible via
imap.   What I'm wondering is if there is a general consensus about
the file format for long term storage that would be most likely to
permit direct search and access from some future mail reader, possibly
on some other OS.  I suppose I could make a VM image that I could fire
up as an imap server again, but that seems kind of cumbersome.
