我正在使用来自网站的 PHPMailer 类，该类将用户 ajax 上传确认发送到我的客户端。这使用 mail.myclient.com SMTP 主机。这是我的客户用于他的 Outlook 检查他的电子邮件的同一个 SMTP 主机。

尽管我收到了来自客户的两封关于邮件传递失败的电子邮件：将消息返回给我用来发送确认电子邮件的相同地址的发件人，但来自网站的这封电子邮件发送没有错误。

这两个问题可以关联吗？我需要提供更多信息吗？

非常感谢！

这很可能是无害的。

In the beginning, there was a warning E-Mail about a delayed transmission (probably one of the E-Mails your client sends out). A mail server could not be reached for 48 hours, maybe because it was down. (That is not an "undeliverable" report - the mail server will still try to send the mail out. If you hear nothing further, the message was eventually received.)

This warning was sent to root@hp13.hostpapa.com (for whatever reason I don't know, you'd have to check the outgoing E-Mails for that address. Do you have a specific errors-to header specified?)

The root address however, doesn't exist or doesn't accept mails, so an error message gets dispatched to the original sender.

It doesn't make 100% sense because it's not clear why root@hp13.hostpapa.com was contacted in the first place - maybe because hp13.hostpapa.com is the outgoing mailserver. As I said, try adding a errors-to: xyz@xyz.com and watch where such notifications end up in the future.

Anyway, the root of the cause looks harmless: It can happen (although it should be rare) that a recipient's mail server is down for 48 hours.
