I would like to enable system-wide filtering so I can define some custom spam filtering. I am using the Ubuntu/Debian split configuration for Exim but cannot see where to define the system filter.
In a normal configuration, I would just the following to the main configuration:
system_filter = /etc/mail/exim.filter system_filter_user = Debian-exim system_filter_group = Debian-exim system_filter_file_transport = address_file system_filter_pipe_transport = address_pipe
However, I am unsure as to where to add these in the split configuration setup.
