Fatal Error ...?

[zulfahmi andri]

Hi Everybody,
I installed qmail --> running well
I tried .qmail-test for user-test@host  ---> Success.
I installed ezmlm ---> ezmlm-manage seem running, but when I sent 
user-list-subscribe@host (from another computer running win 95) I got this
line of returned message :

ezmlm-manage: fatal: I do not accept messages at this address (#5.1.1)

Somebody know how to solve this?
