Question

我正在尝试让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，而不是将退回邮件发送给发件人。

到目前为止，我无法在测试程序中完成任务（见下文）。

发件人是“joe@acme.com”。我想要退回邮件，只能转到“bounce@acme.com”

我正在尝试设置回复地址和Return-Path：标头，但跳出不会转到bounce@acme.com，只能转到joe@acme.com

当查看退回邮件的标题时，Return-Path：标头将设置为发件人joe@acme.com，而不是按照我希望的方式设置为bounce@acme.com。

我正在使用javamail 1.4

提前感谢您提供任何帮助或提示

Answer 1

您需要设置“信封来自”地址。有关可用于设置它的属性，请参阅com.sun.mail.smtp包的javadocs，或使用SMTPMessage类进行设置。

然后希望邮件服务器弹出消息是正确的，并遵循规范......

此stackoverflow post说明您需要设置发件人使用MimeMessage。 addFrom（）并且您需要设置“mail.smtp.host”
