Router doesn't route and no error message

I have a strange problem… when attaching a special word document, the router doesn’t deliver the message to the next server… and I’ve got no error message… if I send another doc, no problem… how is it possible to debug the ROUTER… it isn’t SMTP. ???

Thx !
