Shalom Maaz,

This solution is likely to blow up on any server that has number of recienets limited. This is a common anti-spam measure so that if a spammer finds a way to queue his/her junk, the server doesn't send it because spammers are greedy and want to send to 10000 recipients.

You may find it more practical to create a user list based on /etc/mail/virtusertable and use a for loop

while read -r recipeint
do
mail -s "service warning" $recipient
done < list

Thanks SEP, and sory for repling late.

ok what I understand is I have to create a file, and past the code in the file and execute it ..ok
say
# vi mail.sh
while read -r recipeint
do
mail -s "service warning" $recipient
done < list

then
# ./mail.sh
right ?
now here I wana ask you that wahts "list" and "recepeint" ..

>>> now here I wana ask you that wahts "list" and "recepeint" ..

list is a file with the lists of mail accounts, and recipient is "one" account on each loop.

Shalom,

Script looks good to me. Do make sure the part that sends the mail works right before running the script.
