Hello,
i wan't to use amavisd-new as an proxy filter for rejecting spam- &
virusmails.

i think i have to change the amavis-settings too:
use strict;
# ADMINISTRATORS:
# Debian suggests that any changes you need to do that should never
# be "updated" by the Debian package should be made in another file,
# overriding the settings in this file.
#
# The package will *not* overwrite your settings, but by keeping
# them separate, you will make the task of merging changes on these
# configuration files much simpler...
# see /usr/share/doc/amavisd-new/examples/amavisd.conf-default for
# a list of all variables with their defaults;
# see /usr/share/doc/amavisd-new/examples/amavisd.conf-sample for
# a traditional-style commented file
# [note: the above files were not converted to Debian settings!]
#
# for more details see documentation in /usr/share/doc/amavisd-new
# and at http://www.ijs.si/software/amavisd/amavisd-new-docs.html

# You should:
# Use D_DISCARD to discard data (viruses)
# Use D_BOUNCE to generate local bounces by amavisd-new
# Use D_REJECT to generate local or remote bounces by the calling MTA
# Use D_PASS to deliver the message
#
# Whatever you do, *NEVER* use D_REJECT if you have other MTAs *forwarding*
# mail to your account. Use D_BOUNCE instead, otherwise you are delegating
# the bounce work to your friendly forwarders, which might not like it
at all.
#
# On dual-MTA setups, one can often D_REJECT, as this just makes your own
# MTA generate the bounce message. Test it first.
#
# Bouncing viruses is stupid, always discard them after you are sure the AV
# is working correctly. Bouncing real SPAM is also useless, if you cannot
# D_REJECT it (and don't D_REJECT mail coming from your forwarders!).
$final_virus_destiny = D_DISCARD; # (data not lost, see virus
quarantine)
$final_banned_destiny = D_BOUNCE; # D_REJECT when front-end MTA

$virus_admin = "postmast...@$mydomain"; # due to D_DISCARD default
# Set to empty ("") to add no header
$X_HEADER_LINE = "Debian $myproduct_name at $mydomain";
# REMAINING IMPORTANT VARIABLES ARE LISTED HERE BECAUSE OF LONGER
ASSIGNMENTS
How do i do that?
tnx
