从多个收件人bash脚本使用sendmail

问题描述：

我运行bash脚本cron中当某个条件得到满足将邮件发送给多个收件人。

I'm running a bash script in cron to send mail to multiple recipients when a certain condition is met.

我有codeD这样的变量：

I've coded the variables like this:

subject="Subject"
from="user@domain.com"
recipients="user1@gmail.com user2@gmail.com"
mail="subject:$subject\nfrom:$from\nExample Message"

和实际的发送：

echo -e $mail | /usr/sbin/sendmail "$recipients"

的问题是，只有user2@gmail.com正在接收的电子邮件。我怎样才能改变这种做法，所有收件人收到邮件？

The problem is that only user2@gmail.com is receiving the email. How can I change this so all the recipients receive the email?

请注意：该解决方案必须与sendmail的，我使用的jailshell，它似乎是唯一可用的方法

NOTE: The solution has to be with sendmail, I'm using jailshell and it seems to be the only available method

答

试着做这样的：

recipients="user1@gmail.com,user2@gmail.com,user3@gmail.com"

和另一种方法，使用shell的这里-DOC 的：

And another approach, using shell here-doc :

/usr/sbin/sendmail "$recipients" <<EOF
subject:$subject
from:$from

Example Message
EOF
