Java Mail:将退回的邮件发送到与发件人不同的地址 [英] Java Mail: Getting Bounced Messages To Go To An Address Different From The Sender

问题描述

我正试图让Java邮件将退回的电子邮件发送到与发件人地址不同的地址，而根本不将退回的邮件发送给发件人.

I'm trying to get Java mail to send bounced email to a different address than the sender's address and not send the bounce message to the sender at all.

到目前为止，我无法在测试程序中进行任何操作(如下所示).

So far I can't do either in a test program ( below ).

发件人为"[e-mail]". 我希望发送退回邮件，并且只发送到"[e-mail]"

The sender is "[e-mail]". I want bounce messages to go and only go to "[e-mail]"

我正在尝试设置回复地址和Return-Path:标头，但退回邮件不会发送到[e-mail]，而只会发送到[e-mail]

I'm trying setting both the reply-to address and the Return-Path: header, but the bounces do not go to [e-mail], only to [e-mail]

查看退回邮件的标头时，Return-Path:标头已设置为发件人[e-mail]，而不是按我希望的方式设置为[e-mail].

When looking at the header of the bounce message the Return-Path: header is getting set to the sender, [e-mail], not to [e-mail] the way I want it to be.

我正在使用javamail 1.4

I'm using javamail 1.4

This stackoverflow post explains that you need to set the sender's from using MimeMessage.addFrom() and that you need to set the "mail.smtp.host"
