A transport filter is a *filter*; it runs in parallel with the
actual delivery process. Therefore, the message is being delivered while
it is running. For example, a connection to a remote host has already
been made, and the envelope has been transmitted. All you could do would
be to kill the delivery untidily in the middle.
Transport filters are intended for making modifications when messages
are transmitted. They are not intended to make decisions about delivery.
That is the job of the routers and the system filter and/or the ACLs.
If you want to discard a recipient based on message content, you should
find a way of doing it earlier. For example, you can write a
local_scan() function to do this a reception time.

There is nothing you can do here that will discard the message.
