forward not working

Hallo,
In the past I had a maillist called [email protected]
We have removed that maillist and created a forward. The forward is: [email protected]

But now I got a error:

The mail system

<[email protected]> (expanded from <[email protected]>):
unknown user: "iedereen"
​

other forward and new forward works perfectly... what is wrong?

Thanks

I try to comment-out everything in that file, run postmap and restart postfix but still unknown user.

 

Bump!

 

I have try your command. But still unknown user.

 

Fixed!!

I did:
postalias transport-mailman
postalias virtual-mailman

then restart postfix and mailman
