Wow. That's a pretty big requirement.
Does UW-IMAP have Maildir support?
If so, consider using a program (such as what comes with maildrop) to
"split" an MBox file into individual messages (you may need the -f
switch as well), and have the 'delivery' program use maildrop to (re-)deliver
to a Maildir. Then, move their Mail file out of the way and UW-IMAP
can pick up mail from the Maildir. I have no idea how to configure
UW-IMAP to check A, then B where A is Maildir and B is Mbox (or
vice-versa).
Consider:
=== convert.sh ===
#! /bin/sh
set -e
SOURCE="$HOME/Mail"
# Note: DESTINATION had better be the same as what
# maildrop uses for DEFAULT
DESTINATION="$HOME/Maildir"
export MAILDROPDEFAULT="$DESTINATION"
if test -d $DESTINATION;do
if test -e $DESTINATION; do
echo "$DESTINATION exists but is not a directory! Aborting!"
exit 1
fi
echo "$DESTINATION doesn't exist, creating..."
maildirmake $DESTINATION
fi
reformail -s ./deliver.sh < "$SOURCE"
=== convert.sh ===
=== deliver.sh ===
exec maildrop -V0 maildropfilter
=== deliver.sh ===
=== maildropfilter ===
to $DEFAULT
=== maildropfilter ===
Note: The above is a cut-and-paste but untested from my home.
I'm *sure* there are better MBox-to-Maildir utilities out there.
Which reminds me.
Sam?
Would you consider writing a scaled-down version of maildrop that is
similar to safecat, or are people just better off using safecat if they
want a *small*, **fast** stdin-to-file-in-a-maildir utility?
(Such as what might be useful for this problem.)

Consider altering the procedure above to use 'safecat'.
These are just *suggestions*.
