发送多个收件人而不泄露其他收件人 [英] Email multiple recipients without revealing other recipients

问题描述

我正在使用javamail将电子邮件发送到收件人列表，但不希望他们能够看到其他人收到的电子邮件。我也不想使用BCC发送它，因为用户甚至没有看到自己在TO列表中。我以为这个代码会这样做，但是它显示了TO列表中的所有收件人。除了创建循环和一次发送电子邮件之外，还有另一种方法吗？

I'm using javamail to send emails to a list of recipients, but don't want them to be able to see who else received the email. I also don't want to send it using BCC since then the user doesn't even see themselves in the TO list. I thought this code would do it, but it shows all the recipients in the TO list. Other than creating a loop and sending the emails one at a time, is there another way to do this?

（注意：recipient []是一个包含电子邮件的字符串数组地址。）

(NOTE: recipients[] is a string array containing the email addresses.)

javax.mail.internet.InternetAddress[] addressTo = new javax.mail.internet.InternetAddress[recipients.length];

for (int i = 0; i < recipients.length; i++)
{
    addressTo[i] = new javax.mail.internet.InternetAddress(recipients[i]);
}

msg.setRecipients(javax.mail.Message.RecipientType.TO, addressTo); 

推荐答案

不，没有办法与电子邮件。

No, there isn't a way to do this with email.

您必须明确构建并发送每个收件人迭代的邮件，其中一个作为您的 addressTo array。

You have to explicitly build and send an email iterating by each of your recipients, one of them as the sole member of your addressTo array.
