Drop the rejects from a forwarded alias

[Randy Ramsdell]

Hi,

I am going to have to implement something that drops rejected mail from 
one of our aliases.

The scenario is that we forward to a external server and cannot match 
its spam/UCE rules so our server backskatters mail.

One way would be to drop all rejects. I think this will work because our 
server handles the $users and only forwards known.

Or what would be the best practices way?

Thanks,
