Pop and systems accounts

[Director tecnico del Nodo Nicarao -- Juan Navas]

I'm still having problems setting up a pop account without a system
account.Everything has been ok so far. I can send mails from anywhere and
qmail redirect everyone to the non system pop account test mailbox
(./qmail/popboxes/domain-com/test).But when I try to check these mails the
system tells me that the password is incorrect for the user test (I use
the password testpw -- DmIMm9e5Hc8ic).

# telnet mailhost 110
Trying mailhost...
Connected to mailhost.
Escape character is '^]'.
+OK QPOP (version 2.53) at mailhost starting.
USER test
+OK Password required for test.
PASS testpw
-ERR Password supplied for "test" is incorrect.
+OK Pop server at mailhost signing off.

It seems to me that qpop doesn't recognize the password file (poppasswd) 
that is located on ./qmail/users

**** poppasswd ****
testid:DmIMm9e5Hc8ic:popuser:./qmail/popboxes/domain-com/test 
**** poppasswd ****   

popuser is a valid system account with a proper group and user ID.


Here's what I have on ./qmail/users/assign


=domian-com-test:popuser:888:888:./qmail/popboxes/domain-com/test:::
.

Should I run an additional daemon ir order to make this password file
valid for qpop? I did believe that only qpop was necessary.
