first, I'd recommend to increase debug level of postfix (if it doesn't
totally flood your logs):
/etc/postfix/master.cf:
# Postfix master process configuration file. For details on the format
# of the file, see the master(5) manual page (command: "man 5 master").
#
# Do not forget to execute "postfix reload" after editing this file.
#
#

# service type private unpriv chroot wakeup maxproc command + args
# (yes) (yes) (yes) (never) (100)
#
========================================================================

smtp inet n - n - - smtpd -v <= !!!
#smtp inet n - n - 1 postscreen
#smtpd pass - - n - - smtpd
smtpd -v instead of smtpd -- that will hopefully give some more insight.
