fc3 的 pop3 怎么设呀? 高手指点!

下面是我的devecot.conf
disable_plaintext_auth = yes
login = imap
login_user = dovecot
login = pop3
default_mail_env = maildir:~/mail:INDEX=/var/indexes/%n
mbox_locks = fcntl
auth = default
auth_mechanisms = plain
auth_userdb = passwd
auth_passdb = pam
auth_user = root
auth_verbose = no
protocols=imap pop3

报错:
[root@localhost root]# telnet xxx.xxx.xxx.xxx 110
Trying xxx.xxx.xxx.xxx...
Connected to xxx.xxx.xxx.xxx ( xxx.xxx.xxx.xxx).
Escape character is '^]'.
+OK dovecot ready.
user xxx
+OK
pass xxxxxxx
+OK Logged in.
* BYE Internal login failure. Error report written to server log.
Connection closed by foreign host.
这是怎么回事?
请高手赐教
