I cannot reproduce this here (2.6.7, ix86, spool on Reiser for
testing) and this just looks extremely strange, your df (and stat) and
exim debuglog do not match. - exim ran statfs (actually statfs64) on
/var/spool/exim4 and came up with
f_bavail=0
f_ffree=4096
which does not match your df and stat-info.

Please stop exim, and run
strace -o /tmp/straceout -vf -s 132 exim4 -d -bd 2>&1 |\
   tee /tmp/exim.debug

as root, connect as user:

{ sleep 1 ; echo EHLO localhost ; sleep 1 ; \
  echo 'MAIL FROM:<ametzler@downhill.univie.ac.at> SIZE=10000000' ; \
  sleep 1 ; echo quit ; } |\
 telnet localhost smtp

kill the exim running as root with <Ctrl>-C and send this info:
1) The output of 
   grep -2 -E 'stat.*/var/spool/exim4' /tmp/straceout
2) The corresponding "spool directory /var/spool/exim4 space..."-line
in /tmp/exim.debug

3) The output of "stat -f /var/spool/exim4".
        thanks, cu andreas
