Thank you. But can you explain the matter a little more.

schwach.de is hosted by an ISP. The ISP collects the mails with its mail
server. My machine fetches the mails via POP3. So my machine gets the
mails. Postfix should control that mails from the domain schwach.de are
passed to mailman, from other domains are passed to cyrus. Is not this
controlle by the file /etc/postfix/transport ?
