Mail stuck in wf_notification_out with status = ready

Question

Hi All,
Please help on workflow mailer .
EBS R12 12.1.3 DB:11GR2 OS: OUL5X64
when sending a test mail and verify with this script below , i could see the message was in wf_notification_out table with status READY
BUT IT JUST SAT THERE AND NEVER GOES ANYWHERE.
SELECT n.begin_date,
n.status,
n.mail_status,
n.recipient_role,
de.def_enq_time,
de.def_deq_time,
de.def_state,
ou.out_enq_time,
ou.out_deq_time,
ou.out_state
FROM applsys.wf_notifications n,
(SELECT d.enq_time def_enq_time,
d.deq_time def_deq_time,
TO_NUMBER((SELECT VALUE
FROM TABLE(d.user_data.parameter_list)
WHERE NAME = 'NOTIFICATION_ID')) d_notification_id,
msg_state def_state
FROM applsys.aq$wf_deferred d
WHERE d.corr_id = 'APPS:oracle.apps.wf.notification.send') de,
(SELECT o.deq_time out_deq_time,
o.enq_time out_enq_time,
TO_NUMBER((SELECT str_value
FROM TABLE(o.user_data.header.properties)
WHERE NAME = 'NOTIFICATION_ID')) o_notification_id,
msg_state out_state
FROM applsys.aq$wf_notification_out o) ou
WHERE n.notification_id = &NOTIFICATION_ID
AND n.notification_id = de.d_notification_id(+)
AND n.notification_id = ou.o_notification_id(+);
Here was the result.
BEGIN_DATE STATUS MAIL_STATUS RECIPIENT_ROLE DEF_ENQ_T DEF_DEQ_T DEF_STATE OUT_END_TIME OUT_DEQ_TIME OUT_STATE
11-JUN-12     OPEN      MAIL     TEST.USER      11-JUN-12     11-JUN-12     PROCESSED     11-JUN-12          READY
