Hello,

because there are so many different kinds of "bounce" notifications, I 
suppose you have bad luck with a particular header check.

You also cannot ensure that the server generating a valid bounce message 
can be determined by the mail address.

Maybe you can track, which user send mail to whom, and try to determine 
the failed recipient from the bounce notification and match this against 
the database. But, well, there will be problems there,too, e.g. we have a 
partner, that's using Lotus Notes internally, and the bounce messages 
contain the _Notes_ id, rather than the EMail address.

Bye,
