Using SmartList with Exim4
--------------------------

If your MTA is exim4, you should make the following change to the
default configuration before using smartlist:

*) Edit /etc/exim4/conf.d/main/01_exim4-config_listmacrosdefs if your
configuration is split into small files.

*) Edit /etc/exim4/exim4.conf.template if not.

*) Add the following line below "MAIN CONFIGURATION SETTINGS"

SYSTEM_ALIASES_PIPE_TRANSPORT = address_pipe

*) Then run update-exim4.conf.
