Mail for external User

I have a domain bau-recht.ch

Localy there are some postfix users like

aarau@bau-recht.ch and so on

The real mailserver is an external server and i get the with fetchmail.

There is another location in another town the use the same domain
bau-recht.ch an the get here mails by outlook.

Now when i have to send som mails to one of these users not in our own
office they can't be sent. I get an error like:

Dec 31 12:18:30 localhost postfix/qmgr[10864]: 3232EE1B1D:
from=<testuser@bau-recht.ch>, size=1824, nrcpt=1 (queue active)
Dec 31 12:18:30 localhost postfix/local[10895]: 3232EE1B1D:
to=<test@bau-recht.ch>, relay=local, delay=0, status=bounced (unknow
n user: "test")

How to tell postfix to send mails without local user to an external mail
host like any other mail like something@bluewin.ch ?

tnx

Create a file /etc/postfix/transport with lines like

testuser@bau-recht.ch smtp:[204.202.241.5]


where that's the IP address of the actual server for testuser.
You are overriding the default delivery method for that address.
The square brackets say that is the actual host, don't try
to look up an MX record.
Compile the file with postmap so you have a transport.db file.
Mention the file in /etc/postfix/main.cf like this

transport_maps = hash:/etc/postfix/transport

Restart Postfix.

I asume my ip Address is the one my external SMTP Server use it? It's
195.186.19.155

(my local mailserver from whitch i will send mail has 192.168.10.50 but
this will also give me back an error (something like "user test" unknown.

But now i get this messages in my log

I assume from the log that things should be the other way round,
with testuser@ being the local account and test@ the account
that is accessed directly via Outlook, so your transport should
in fact look like:
test@bau-recht.ch smtp:[195.186.19.155]

So you need authentication, as bluewin seems to have a
policy that only allowes their own trusted MXs and authenticated
clients to submit mails to this server.

You'll have to configure the postfix SASL client according to
http://www.postfix.org/SASL_README.html#client_sasl
to make things work then.
