I try to setup my Mailserver. Version 1.4.1 on a Ubuntu machine.

The server is runs on with no Problem
but today i recive a new Server   
and i try to load the mails from the server.
The mail loaded by fetchmail but it can´t delivered so it flushed.

I checked the header in webmail and found this

<code> 
X-Original-To: info@mydomain.de
Delivered-To: m15846d0@ddsued.kasserver.com
<code/>

So i think fetchmail delivers to "Delivered-To"

So i try to add "Envelope" to my fetchmailrc

Now it looks like that

poll fjlsljfljs.kasserver.com with proto POP3 
envelope 'X-Original-To:'
localdomains mydomain.de:   
user 'kfsdjljfl' there with password 'secret'
to * here  smtphost fw.otherdomain.de

But it don´t work.

Can someone explain me the "Envelope"
I thought envelope reads the X-Original-To: in the Header
and delivers to this adress.

im Right ? or i have to activate the envelope feature before ?

THANK YOU !
