Java Mail: Getting Bounced Messages To Go To An Address Different From The Sender

Question

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.

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

The sender is "[email protected]". I want bounce messages to go and only go to "[email protected]"

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

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

I'm using javamail 1.4

Thanks in advance for any help or tips

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"
