My advice? Throw away the gateway and find one that works correctly.

Doing this results in your users NOT getting 99.99% of valid/legitimate 
DSN notifications (since they all use the NULL sender, as prescribed by 
the RFCs).

Blocking all messages with a NULL sender is not only violating the RFCs, 
and will possibly result in your getting on certain blacklists, like 
dsn.rfc-ignorant.org, it is lazy and dumb.

But, to each his own...
