You could use the system filter. I have a couple of scripts that I use
for calling SA from the system filter:
http://satools.sourceforge.net/routespam.html
Read that whole page. You'll find a snippet of Exim filter code like
this:
# If this message originated locally, or if it has already been
# processed by spamcheck, then stop processing now. Send it on as-is.
if ($received_protocol is "local" or
$received_protocol is "spamc" or
$sender_host_address is "127.0.0.1" or
$h_X-Spam-Flag: is not "") then
finish
endif
followed by piping the message to my routespam script, which runs spamc
and interprets its output.
You would obviously want to change this so locally-originating messages
are still scanned:
if ($received_protocol is "spamc" or
$h_X-Spam-Flag: is not "") then
finish
endif
With that small change, the tools at satools.sourceforge.net should be
useful for you.
