Either use it in IMAP mode (you can do that even while it's talking to
the Exchange server, I'm told) or use a real, standards-compliant mail
program instead. Starting a new broken-thread without 'Re:' in the
subject line deliberately to get round the automatic filters will just
get you into the blacklist. :)

Talk to your IS department. Surely they have a responsibility to provide
you with a configuration which allows you to behave as a responsible
citizen in your interaction with the outside world?

There's been quite a bit of work on the NAND drivers recently. Look at
the linux-mtd-cvs list archives and pick a date before the recent flurry
of activity, or try current CVS.

If you can reproduce this today, it would be interesting to do so with
'CONFIG_JFFS2_FS_DEBUG=1' while you're writing and subsequently
remounting and trying to read the file.

Less interesting.

Can you be more precise about what happens?
