Put a wrapper around the aliases, for example:

list-name at listserver.com	"|/usr/bin/mywrapper|/home/mailman/mail/mailman post list-name"

Then the script mywrapper could be like this:

#!/bin/bash
while read line
do
echo "$line"
done

fortune=`/usr/games/fortune`

echo "-- "
echo $fortune

However, I'm not sure that double pipes are allowed in sendmail or
Postfix. This is just a quick idea. Maybe you can pipe the output from
mywrapper directly to the "mailman post" command, like this...

Aliases file:

list-name at listserver.com	"|/usr/bin/mywrapper"

--- START SCRIPT ---
#!/bin/bash
# Simple filter to add footer to email read from stdin

# Define a temporary filename
TMPFILE=msgfile

# Delete the temporary file if it already exists
if [ -f $TMPFILE ]; then
rm $TMPFILE
fi

# read from STDIN line by line, outputting to temp file
while read line
do
echo "$line" >> $TMPFILE
done

# Now get the output from Fortune ;-)
fortune=`/usr/games/fortune`

# Add RFC footer/signature delimiter
echo "-- " >> $TMPFILE

# Now add the fortune we got above
echo $fortune >> $TMPFILE

# Now use cat to redirect the output of $TMPFILE to mailman
/bin/cat $TMPFILE | /home/mailman/mail/mailman post list-name

--- END SCRIPT ---

Notes:

- Please let me know if this was useful to anyone.
- This will break posts with attachments, it is ONLY good for plaintext
  posts. If you want to get cleverer with files with attachments your
  script will have to be MIME aware.
