Correct. In particular, "filter.txt" supplied with Exim notes:
----------------------------8< cut here >8------------------------------
Remember that, as was explained earlier, the pipe command is not run at the
time the filter file is interpreted. The filter just defines what deliveries
are required for one particular addressee of a message. The deliveries
themselves happen later, once Exim has decided everything that needs to be done
for the message.
A consequence of this is that you cannot inspect the return code from the pipe
command from within the filter. Nevertheless, the code returned by the command
is important, because Exim uses it to decide whether the delivery has succeeded
or failed.
