I'm starting the daemon as root.
I sometimes HUP the daemon, but nothing changes.
Two binaries are identical, because I just copied exim-4.02-10.daemon
from exim-4.02-10 by 'cp' command. So time stamps are different.
(Of course, exim-4.02-10 is the original version, installed by
'make install' command.)
Now, what I think strange is, that exim can deliver mails to users'
home directories under users' ownership with 700 permission.
It seems exim can setuid to some user in appendfile driver, but
can not in redirect driver?
