Hello

I used bogofilter with Exim in transport spamcheck, then decided to change to 
use junkprobe.so [1] with bogofilter ( ${dlfunc API and Exim's queue ).

${dlfunc [2] it is similar to local_scan() [2] API method, and requires 
local_scan API for Exim 4.52 [2] or later with EXPAND_DLFUNC=yes set in 
Local/Makefile.

It is based on ${dlfunc string expansion method and a series of ACL's. As a 
result of calling the ${dlfunc string expansion, our own library is loaded, 
and it has access to local_scan() API and Exim's queue.

In its normal mode of operation, junkprobe.so [1] with bogofilter takes an 
email message, and returns a status indicating whether or not the message is 
spam:

No, score=0.000 required=9.90e-01 tests=[bogofilter]
   learn=no time=0.0465secs on <primary_hostname>


+ Exim configuration:

This ${dlfunc with bogofilter need bogofilter installed and configured.
junkprobe.so with bogofilter has default use directory
for loading and saving word lists, '${spool_directory}/junkprobe/bogodir'.

In order for the library to be called, you need to add the
following lines into the Exim configuration file, ACLs section
(begin acls), in the acl_check_data ACL:

-----
# Test using global database (empty datadase directory to use default):
 warn   condition = ${if <{$message_size}{250k}}
   set acl_m_bogo  = ${dlfunc{/usr/lib/exim/junkprobe.so}{bogofilter}\
			{}{-o 0.90 defer_ok}}

# Reject spam if score = 1:
 deny   condition = ${if match{$acl_m_bogo}{score=1}}
          message = Spam not welcome [spam=$acl_m_bogo]
            delay = 5s

# Adding header:
 warn   condition = ${if def:acl_m_bogo}
       add_header = X-Bogo-Status: $acl_m_bogo
-----
# Test using user database:
 warn   condition = ${if <{$message_size}{250k}}
   set acl_m_bogo  = ${dlfunc{/usr/lib/exim/junkprobe.so}{bogofilter}\
			{$acl_m_userpath/bogo}{-o 0.95 defer_ok}}
       add_header = X-Bogo-Status: $acl_m_bogo
