AHHA!!
The second one would be the one I would like and the first one is the one I would NOT like. |

No, this is a delivery agent (mail going out of Postfix) not a submission
service (mail coming into Postfix). The cleanup service override is used
when needed with smtpd(, pickup( and qmqpd(.
The entire problem is addressed much better in 2.1 and later via
receive_override_options (and it that is not enough, use multiple
Postfix instances, search the archives, you don't need to ask here).

Ouch. This was left there from the time, when I used smtp instead of lmtp.  |

Okay. I understand that now. |

Will do. Sometimes is hard to read stuff not written in my native language. When I ask, then I mostly get an answer and I can interactive get to my point. Just reading a document and having no one to ask is sometime not very easy. Anyway... Thanks for pointing me to the correct direction. |

you should use pre-cleanup in pickup. otherwise, address manipulations

If I do that, then I get exactly this "user unknow" error.
The advice is wrong unless you also set a content_filter for pickup.
If you don't need/want to scan locally submitted mail, you must not
direct pickup at "pre-cleanup".
ahem? so it's write to direct both pickup and 127.1:10025 to cleanup, |
which means running through virtual aliases twice? |

What's right depends on the context. In this case, virtual rewriting
should be disabled for the cleanup( used by the submission daemon
(smtpd( or pickup() if content filtering is enabled for the same
daemon. If filtering is disabled, virtual rewriting must be enabled.

and conversely, the advice is right unless you wanna do something else. |
after all, it's all about default configs vs special configs...

and thus scanning the same message twice?

I meant "it's right" and not "it's write". |

whatever is the theory, the situation here depends on nothing. if you
use virtual aliasing, canonical stuff, ... in both pickup and in the
post-filter postfix, you'll run into problems. If I'm mistaken, I'm
ready to get corrected, but I don't see why one should do virtual
aliasing/addr manips/... at both pickup and in the after filter smtpd. |

Possibly, IF CONTENT FILTERING IS ENABLED for mail injected via
sendmail(1). This was not the case with the OP, hence his problem.
Pay attention.

There's hardly any reason to do so, but in many cases it doesn't hurt
either.
