You can integrate spamassassin in two ways, through calling it through
procmail or by directly integrating it into Exim.
The former is a bit easier to setup, and suitable for single-user
machines.
The latter is a bit more complex to setup, but provides a single point
of configuration. Essentially you will pipe incoming messages to the
spamc daemon and then resubmit them to exim to reinject them into the
pool. A system filter will allow you to do something sensible with
messages submitted from spamc depending on their status.
I use the second configuration to provide a pass-thru host filtering
mail aimed at a corporate Exchange server. Here are some details, which
are additional items to add, if you are brave!, to your exim.conf file.
Main
In the top (Main Configuration) section of the configuration file I
have:
message_filter = /etc/exim/spam_header_rewrite.filter
The filter file contents:
if first_delivery and
$h_X-Spam-Flag: contains YES
then
logfile /var/log/exim/spamlog
logwrite $tod_log From: $h_From: Subject: $h_Subject: \n \t X-Spam-Status:
$h_X-Spam-Status: Sender: $sender_address
deliver [EMAIL PROTECTED]
seen finish
endif
Transports
You may want to do a shadow delivery of mail to a backup area while you
are testing:
shadow_delivery:
driver = appendfile
group = mail
user = mail
mode = 0660
envelope_to_add = true
directory=/home/mailbackup
maildir_format
pipe_to_scanner:
# from
# http://dman.ddts.net/~dman/config_docs/exim3_spamassassin.html
driver = pipe
command = /usr/sbin/exim -oMr scanned-ok -bS
transport_filter = /usr/bin/spamc
bsmtp = all
# the user and group mail have read/write access to this
# folder
home_directory = /tmp
current_directory = /tmp
# must use a privileged user to set $received_protocol on the
# way back in!
user = mail
group = mail
return_path_add = false
log_output = true
return_fail_output = true
prefix =
suffix =
shadow_transport = shadow_delivery
*** Routers
spamcheck_router:
driver = domainlist
condition = ${if eq {$received_protocol}{scanned-ok}{no}{yes}}
transport = pipe_to_scanner
route_list = my.domain

My mail system runs exim and I am wanting to integrate spamassassin
into it too.
I am not sure of the best way to do this, and would appreciate some
assistance with the configuration.
I am using the versions of both packages contained in woody.
