Bounce Management issues in CRM 7.0

Hello All,

I'm currently setting up bounce management in CRM 7.0. Below are the settings i have done in the system.

Handle all hard bounces using dynamic bounce processing(bounce rules)

1. Event Linkage: CRM_DOCU  - ERRORSENDSTATUSREACHED  - BOUNCE

2. Default bounce rule is used with conditions for the communication type = INT & error type = Permanent

      action: update bp address data with do not use flag.

3. SO28:  recipient email add(sender address in the bounce mail) 

                address type: internet address              new recipient: ERMS Support 2(address)

4. SCOT -> Inbound processing:            Communication Type: Internet mail

           recipient address(sender address in the bounce mail)          document class: *

           Exit name: CL_CRM_BOUNCE_HANDLER                                                         Call Seq: 1

5. CRMC_IC_AUIADDR:  (sender address in the bounce mail)

We are recieving the inbound bounce mails and i can see the bounce event triggered. But the rule and the action are not getting triggered and hence the flag is not set.

I did check out all the links in SDN and also followed the steps mentioned in ERMS Overview by John Burton.

Please let me know if I'm missing any setting?

Thanks in advance,

Madhu
