CCMS not triggering Mail

Dear Experts,

I have configured CCMS alert configuration from RZ21 and RZ20 but we are not getting any mail alert from the system.

1. created private distribution list in 000

recipients : DEV:380:TESTUSER  type (remote mail )

                   DEV:380:TESTUSER1 type (remote mail)

1. RZ21 configuration done as below,

   2.1 selected the node CCMS_OnAlert_Email

   2.2 Set sender, Receiver (Given distribution list), Type (P)

   2.3 Selected "Auto reaction method" under Release tab

1. RZ20 Configuration done as below,

   3.1 Selected "SAP CCMS Monitor Templates"

   3.2 Selected "System Errors" node

   3.3 Selected the node "Abap Shortdumps" and in properties, under Methods tab selected "CCMS_OnAlert_Email" in Auto-reaction method filed.

Please note that SCOT settings are configured properly and i can send a mail to external mail ID from SBWP. also i have maintained mail IDs in SU01 for TESTUSER and TESTUSER1 with Remote mail communication method.

System details: SAP netweaver 7.31 on Oracle 11 G, OS:Windows 2008 R2 server

Please let me know what is missing.

Thanks in advance!
