postfix to INN

Hello,

I'am new to this group, so forward me to an other if better fitted, 
thank you :-)

I'm building a postfix server on a hosted machine, alone for his IP. I 
write down what I do here:

http://www.dodin.org/wiki/pmwiki.php?n=Doc.PostfixConfigure

it works, at least from my tests.

Now my goal is to join a mailing list to the INN server of this very 
server.

http://www.dodin.org/wiki/pmwiki.php?n=Doc.ConfigurerINN

I used to do it with mailman, but now I have to sync a sympa server (of 
course not on my server, but I manage part of it).

My own server is dodin.fr.nf both for INN and postfix (ports 119 and 25)

On the mailing list server, "culte.org", I add a "test" list for this 
purpose. I add also an user "[email protected]" in the mailing list, for 
this user to receive the mails from the list.

I add in /etc/aliases (and run newaliases)

test: "| /usr/lib/news/bin/mailpost test"

but sympa keep saying that the user test is in error "Bad destination 
mailbox address"

what's wrong? is it necessary to add a real user test on the postfix server?

thanks
jdd
