Доброй день всем!
Ребята, строю почтовый релей для внутреннего корпоративного сервера Exchange с фильтрацией спама на CentOS 5.2.
Установил postfix 2.3.3. Нстроил. Проверяю хождение почты по средствам телнета. Письма постфикс принимает, обрабатывает и передает нормально на Exch 2003.
Далее прекрутил spamassassin 2.5.2. Проверяю хождение почты, и тут происходит зацикливание отправленного на poistfix письма.
Прикручивание SA к Postfix делал по этой статье:
http://www.akadia.com/services/postfix_spamassassin.html

(текст скрипта для spamassassina вот:)
#!/bin/sh

# -----------------------------------------------------------------
# File:        relayspam
#
# Purpose:     SPAMASSASIN shell-based filter
#
# Usage:       Call this script from master.cf (Postfix)
#
# -----------------------------------------------------------------

# Variables
SENDMAIL="/usr/sbin/sendmail -i"
EGREP=/bin/egrep
SUBJECT=WARNING_SPAM

# Clean up when done or when aborting.
trap "rm -f /var/tmp/out.$$" 0 1 2 3 15

# Pipe message to spamc
cat | /usr/bin/spamc -u filter > /var/tmp/out.$$
# | /usr/bin/spamc -u filter

# Are there more than $SPAMLIMIT stars in X-Spam-Level header? :
if $EGREP -q "$SUBJECT" < /var/tmp/out.$$
then

  # Option 2: Divert to an alternate e-mail address:
  $SENDMAIL spam@orl.unimilk.ru < /var/tmp/out.$$

  # Option 3: Delete the message
  #rm -f /var/tmp/out.$$
else
  $SENDMAIL "$@" < /var/tmp/out.$$
fi

# Postfix returns the exit status of the Postfix sendmail command.
exit $?

Пробую сделать вот так, дабы понять, почему не передается письмо от SA на postfix:
# /usr/sbin/sendmail -i spam@spamstore.test.ru < /root/install.log

Вот, что вижу в логах:
