Quick and dirty:
echo -n "all:" >>/etc/aliases
for i in `cat /etc/passwd |cut -d ':' -f 1`; do
echo -n "$i," >>/etc/aliases
done
echo "aaa" >>/etc/aliases
newaliases
mail all -s "subject" < your.message
Down sides:
Anyone can mail to all@yourhost to distribute tons of spam, so disable
this alias right after using it!
This mails to EVERY account, including system accounts.
Alternative (causes more system load, but doesn't leave the all address
open):
for i in `cat /etc/passwd | cut -d ':' -f 1`; do
mail -s "subject" $i < your.message
done
