Hi Sebastien,

Sounds like you want to use a system filter. This page of the docs has
the whole thing:

http://www.exim.org/exim-html-4.66/doc/html/spec_html/ch43.html

As a sample, here is something I did one a server in the past. First
you need to specify the system filter in the conf file;

system_filter = /etc/exim4/system_filter
system_filter_user = Debian-exim
system_filter_group = Debian-exim
system_filter_file_transport = address_file
system_filter_directory_transport = address_directory

Then you need to build your filter. In sample above, that would be the
contents of /etc/exim4/system_filter:

# Set the logfile.
logfile /var/log/exim4/filter.log 640

# If the incoming message is an error message, drop out of the filter
# and let the bounce proceed as normal. This is a safety net in case something
# is really broken.
if error_message then finish endif

# We only want to do things once so we check for first_delivery.
if not first_delivery then finish endif

if $tod_log matches "\\N^(\\d{4})-(\\d\\d)-(\\d\\d)\\d\\d:\\d\\d:\\d\\d$\\N"
then
    logwrite "$tod_log $message_id $sender_address $recipients $h_subject:"
    unseen save /var/exim/archive/today/
endif


finish

Of course this is just a sample so you get the idea. The above would
store the messages in maildir format in /var/exim/archive/today.

Hope this helps,
mikeS
