Using sendmail from bash script for multiple recipients
I'm running a bash script in cron to send mail to multiple recipients when a certain condition is met.
I've coded the variables like this:
subject="Subject"
from="[email protected]"
recipients="[email protected] [email protected]"
mail="subject:$subject\nfrom:$from\nExample Message"
And the actual sending:
echo -e $mail | /usr/sbin/sendmail "$recipients"
The problem is that only [email protected] is receiving the email. How can I change this so all the recipients receive the email?
NOTE: The solution has to be with sendmail, I'm using jailshell and it seems to be the only available method
Answer
Try doing this :
recipients="[email protected],[email protected],[email protected]"
And another approach, using shell here-doc :
/usr/sbin/sendmail "$recipients" <<EOF
subject:$subject
from:$from
Example Message
EOF
Be sure to separate the headers from the body with a blank line as per RFC 822.
