I once "converted" Netscape mailbox files to VM files. The problem that
I had is different from the problem that is described here, so I think
something else is going on here. Anyway, my problem was that some of the
messages stored in Netscape didn't have an empty line, which VM needed
as a separator between messages, before they began. The effect was that
if I just used Netscape mailbox files in VM, VM would show fewer number
of messages because a few of the adjacent messages were recognized as a
single message. I fixed this by writing a simple shell script, which I
attach below. I suppose it could be useful to somebody else migrating
from Netscape to VM. The only thing that will be necessary to run the
script is to replace `name-temp-file` to some temporary file name. In my
case, name-temp-file is another shell script to generate a new temporary
file name.
