  • This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it.

• You must have installed the exim-heavy version of exim to enable support for server side filters.
• NOTE: I am using a monolithic exim configuration file (/etc/exim4/exim4.conf.template).
  • If you are using the multiple config version of exim-config let me know.

• place the file system.filter into the /etc/exim4 directory.
• cut and paste the following into the top of the /etc/exim4/exim4.conf.template file:

###########################################################################
## WINLINK 2000 Filter
###########################################################################
system_filter = "/etc/exim4/system.filter"
system_filter_user = Debian-exim                        # Set this to the user that exim runs as
system_filter_group = Debian-exim                       # Set this to the group that exim runs as
system_filter_pipe_transport = address_pipe
system_filter_file_transport = address_file
system_filter_reply_transport = address_reply
system_filter_directory_transport = address_directory

• this must go at the top of the file underneath the following lines:

# Macro defining the main configuration directory.
# We do not use absolute paths.
.ifndef CONFDIR
CONFDIR = /etc/exim4
.endif

• make sure that the wl2k directories for paclink-unix are set for the debian username/group that exim is using.
• By default this is Debian-exim.Debian-exim, this MUST be the same as system_filter_user and system_filter_group.

chown -Rv Debian-exim.Debian-exim /usr/local/var/wl2k

• restart exim:

/etc/init.d/exim4 restart

• create a blank eximfilter.log file in the wl2k folder:

touch /usr/local/var/wl2k/eximfilter.log && chown Debian-exim.Debian-exim /usr/local/var/wl2k/eximfilter.log && \
chmod 666 /usr/local/var/wl2k/eximfilter.log

• all message processing by the filter will be logged into /usr/local/var/wl2k/eximfilter.log
