i think this was covered somewhen last year..
i'm not sure, what the solution was back then, but i'd say

on your "Local" server:
add mx record for "pseudo.one.de"
and alias the "pseudo.one.de" domain to "one.de" domain

.qmail-default:
| /home/vpopmail/bin/vdelivermail '' $EXT@realmx.one.de

on your "NONLocal" Server:
add mx record for "realmx.one.de"
and alias the "realmx.on.de" domain to "one.de" domain.

.qmail-default:
| /home/vpopmail/bin/vdelivermail '' bounce-no-mailbox

.qmail-someuseronlocal:
& someuseronlocal@pseudo.one.de




what does this do?
qmail puts the username part of the "RCPT TO:" email address into the env 
variable EXT (at least i think it does?).
so on your local server vdelivermail will first check, if the user exist on 
the _local_ system ? if no: it forwards the mail to $EXT@realmx.one.de which 
is no local domain, but handled by the NONLocal server.

on the NONLocal server it receives the mail, as realmx.one.de is an 
aliasdomain for one.de it will handle the mail just as expected: if the user 
doesn't exist on this system either, it will bounce the mail.

you just have to make sure, that for each user on the "local" server a 
.qmail-useronlocalname file on the "NONLocal" server exists.
