** so it's not transported, just "redirected" to the new addresses
"userlist" and "user1"

** and this into the local mailbox for "user1"


I'm really sorry, but still I can't see any duplication here. There has
to be something else duplicating the messages...

Would it be possible to access your system via SSH?
May be I can have a look on site. (Not now, but in the
evening, around 20:00 UTC). For details please contact me via
personal mail.


    Best regards from Dresden
