first: look into the ISPs mail server log files.
second: look into the customers log files.
third: if none of the above helps you should try to reproduce the
problem in a way which allows you to see what's going on. This includes
sending large mail from somewhere else to see if that works, and to
send a large mail from the customer to some other mail server. Both
together might help to find the cause of the problem.
fourth: did you set $DATABYTES?
