Failed or refused to load /var/spool/mail/xxxx

Hello guys,

I'm trying to use the popa3d after some years without work with
mailservers (I was working just with webservers on ISP provider).

I'm using the popa3d-1.0.2-1mdv2007.0 package, the server is UP and
listen on 110/tcp port, the postfix it's working and delivering
messages on /var/spool/mail/user as well.

This is the problem:

$ telnet localhost 110
Trying 127.0.0.1...
Connected to orochimaru (127.0.0.1).
Escape character is '^]'.
+OK
user tiagocruz
+OK
pass 123456
-ERR
Connection closed by foreign host.

And this is the error on log:

Jul 18 00:17:36 orochimaru popa3d[12995]: Authentication passed for
tiagocruz -- [127.0.0.1]
Jul 18 00:17:36 orochimaru popa3d[12995]: Failed or refused to load
/var/spool/mail/tiagocruz

I don't have Idea of how can I solve this problem... someone can help me?

Thanks a lot!
