[exim] exim4 and bcc on Debian Etch

Hi,

I have a Debian Etch machine with Exim4 and Cyrus IMAP. It downloads the
emails with fetchmail and Exim4 puts them in the Cyrus folders.

I want to filter the incoming message and it works great with sieve
scripts. Except one thing: I can no filter on bcc because there are no
Bcc lines in the incoming messages.

After some googling I found that maybe Exim4 removes the Bcc line from
the message, and it won't remove it if I call it with the -t command
line option.

But how can I do it? Where should I put the -t?


Thanks,
