当我使用php发送批量邮件时，如何生成交付报告失败（跳出）像gmail？

Question

When I send bulk mail to all of my subscribers , how do I detect successful delivery or bounce? Suppose a few emails on subscriber list are not valid or do not exist, how we can detect that in php?

Answer 1

if sending read receipts is enabled, is that you need to include a new line at the end of every line:

$email_header .= "Disposition-Notification-To: $from
"; 
$email_header .= "X-Confirm-Reading-To: $from
";
