Thank you for your concern Thomas.

Here is the modified script :
###################################
#!/bin/bash

TMP_FILE="/tmp/sendmail-stdin"
TMP_LSOF_FILE="/tmp/sendmail-lsof"
DATUM="`date +%Y%m%d-%H%M%S`"

echo "=====NEW SENDMAIL CALL=======" >> "${TMP_LSOF_FILE}"
echo "${DATUM}" >> "${TMP_LSOF_FILE}"
echo "=== START $$" >> "${TMP_LSOF_FILE}"
lsof -d^mem,^cwd,^txt,^rtd -a -p $$ >> "${TMP_LSOF_FILE}"
echo "=== END $$" >> "${TMP_LSOF_FILE}"

echo "=====NEW SENDMAIL CALL=======" >> "${TMP_FILE}"
echo "${DATUM}" >> "${TMP_FILE}"
echo "========MESSAGE BEGIN========" >> "${TMP_FILE}"
exec tee -a "${TMP_FILE}" | /usr/sbin/sendmail.real "$@"
echo "========MESSAGE ENDED========" >> "${TMP_FILE}"
echo "${DATUM}" >> "${TMP_FILE}"
echo "======END SENDMAIL CALL======" >> "${TMP_FILE}"
####################################

Here are the "sendmail-stdin" log, showing a bad behavior, for 3 mails in a
row :
####################################
=====NEW SENDMAIL CALL=======
20120913-110049
========MESSAGE BEGIN========
========MESSAGE ENDED========
20120913-110049
======END SENDMAIL CALL======
=====NEW SENDMAIL CALL=======

========MESSAGE ENDED========
20120913-110049

20120913-110049
========MESSAGE BEGIN========
========MESSAGE ENDED========
20120913-110049
======END SENDMAIL CALL======
#####################################

And here is the "sendmail-lsof" of the corresponding messages :
