i've pushed an update of my nupas contrib
package to sources.  imap successful in use
with apple mail (snow leper, too), iphone,
outlook, opera, ff, upas/fs.

note on installing:
as devon pointed out, installation is still a
big pain.
1.      move /sys/src/nupas -> onupas
2.      contrib/install quanstro/nupas

if you want to go cold turkey nupas, then
a.      mv /386/bin/upas /386/bin/oupas
b.      mv /386/bin/nupas /386/bin/upas
c. (opt)        edit top-level mkfile to install in
       /386/bin/nupas.

if you want to hedge your bets
a.      add "usenupas" to your profile
b.      edit cpurc as you see fit to use nupas
       binaries.

cavet: i have not had a chance to retest the
contrib package.

as always, feedback welcome.
