problem when compilling imapd :(

[haneo]

I have downloded imapd (

http://www.washington.edu/imap)

i want to compil it so imapd and pop3d read mails from ~user/.mail and not from /var/spool/mail/$USER

from teh doc i changed
in the file src/osdep/unix/env_unix.c , the line
sprintf (tmp,"%s/%s",MAILSPOOL,myusername ());
to :
sprintf (tmp,"%s/.mailbox",myhomedir ());


so i issued:
make lnp;
cp ipopd/ipop3d /usr/sbin/ipop3d

when from another machine i issur:
telnet IMAPD-SEVER 110
+OK POP3 ns.IMAPD-SERVER.dz v2002.81 server ready
user test
-ERR Unknown AUTHORIZATION state command

why this error !!
i have done also :
make clean; make lnp PASSWDTYPE=pmb

also the same the probleme remaine !!!


any suggestion is welcom
