Priority in a bounce.

Thu Mar 28, 2019 8:51 am

Hello, I have a message with the following fields:
Return-Path: <...>
From: <...>
Reply-To: <...>
How does MWP determine where to send a bounce? For what I see, it selects Reply-To instead of Return-Path. I would like to use Return-Path because it's the address where bounces are received in a listserver used to send spam. I've had success before with this method (the listserver erases my account from the list of recipients), but since MWP uses Reply-To the bounce is going to a place that doesn't cause effect (a fake or unattended email of the spammer).

You really should never use bounce unless you know for a fact, it is coming from a valid email address. For example, if you want to bounce emails back to your X wife.

Bouncing spam really never works. In fact it makes things worse because the spammer spoofs - forges another email address in the spam. This means the bounce will never get back the spammer anyway. If the spoofed address is invalid, as is often the case, then it just gets bounced back again. And if the spoofed address is a legitimate address that was stolen from some innocent person, you just end up sending the spam on to that innocent person, adding insult to injury.

Plus, a lot of ISPs don't like bounces because it does not go back to the spammer and may get bounced back again. That just clutters up and wastes more bandwidth.

My advice is don't use bounce.

Hi there

Yeah I think you're right in that it uses the Reply-To and if not found it may then attempt the Return-Path

There's no way to change that unfortunately within MailWasher, we can look to add it to the list, but there's so much other work that would take priority it would be months down the line, not likely this year.
