Extend Notification of Workitem doesn't work

Hi all,

I got a problem while using extend notification of WorkItem .

I made all customizing thru SWN_ADMIN transaction, everything looks ok.

I made cusotmizing in transaction SCOT in order to send mail thru a SMTP server, that works .

I lunch program SWN_SELSEN in order to send work item.

The resutl is nothing is send , the program said that there's an error but i don't find any help.

When i go to transaction SCOT, all mail are not on the node SMTP define but in another node which name is W/O NODE.

Does somebody can help me?
