disclaimer.sh (now with postlog commands) is as follows:

=====================================================================
#!/bin/sh
# Localize these.
INSPECT_DIR=/var/spool/filter
SENDMAIL="/usr/sbin/sendmail -G -i" # NEVER NEVER NEVER use "-t" here.

/usr/local/sbin/postlog -t postfix/disclaimer.sh -- my commandline: $0 "$"

# Exit codes from <sysexits.h>
EX_TEMPFAIL=75
EX_UNAVAILABLE=69

# Clean up when done or when aborting.
trap "rm -f in.$$" 0 1 2 3 15

# Start processing.
cd $INSPECT_DIR || { echo $INSPECT_DIR does not exist; exit $EX_TEMPFAIL; }

cat >in.$$ || { echo Cannot save mail to file; exit $EX_TEMPFAIL; }

/usr/local/bin/altermime --input=in.$$ \
    --disclaimer=/usr/local/etc/postfix/disclaimer.txt \
    --disclaimer-html=/usr/local/etc/postfix/disclaimer.html || \
        { echo Message content rejected; exit $EX_UNAVAILABLE; }

/usr/local/sbin/postlog -t postfix/disclaimer.sh -- sendmail commandline:
"$"

$SENDMAIL "$" <in.$$

exit $?
=====================================================================

/usr/sbin/sendmail is a link to /usr/local/sbin/sendmail the Postfix
sendmail.
