Yes.

My method uses a script, but after you run it the first time you only need
to run it if new users are added *and* you can send emails using any method
you prefer (you don't need to send them from a script).  I run it from a
cron job every night.

1. Add the following lin to the bottom of /etc/aliases (the email address
can be any address on your server, don't make it easy for your users to
guess if you don't want them to use it).
serverusers@xxxxxxxxxx :include:/root/user_list.txt

2. Run this script.

#!/bin/sh

## chmod 0100 generate_user_list.sh
## chown root:root generate_user_list.sh

## Generate user list.
output_file="/root/user_list.txt"
if test -e $output_file
then
rm $output_file
fi
for user in `cut -f1 -d: /etc/passwd`
do
## If want to override environment variable '$HOSTNAME'
## uncomment the following line:
# HOSTNAME="domain.tld"
echo $user@$HOSTNAME >> $output_file
done

## Regenerate aliases database.
newaliases

## Restart sendmail.
sendmail_pid=`head -1 /var/run/sendmail.pid`
kill -HUP $sendmail_pid

3. Email serverusers@xxxxxxxxxx in the bcc: field to hide the email address
from the recipients.
