[exim] Senders filtering problem...

Hello everybody.

New user of exim, I encounter a lot of problems trying to configure it.
Indeed, I first tried to set up a reject of some senders written in a file.
My problem is that the filtering only works when I use the exim -bh
command which runs a fake SMTP session.
When I try to send my email with the traditionnal unix mail fonction,
the email is successfully sent (or it shouldn't since I'm logged as a
blacklisted user).

Where am I wrong?

Best regards.

Johan Mereaux.
