Hi Jeremy,

Thanks for your response.  I'm still missing something ....

All I want to know is whether the following line alone in an existing
/etc/aliases file should or should not allow me to include aliases from
an additional external file:

:include:/etc/aliases.alternate

My system_aliases is defined as:

system_aliases:
  driver = redirect
  allow_fail
  allow_defer
  data = ${lookup{$local_part}lsearch{/etc/aliases}}
  user = exim
  file_transport = address_file
  pipe_transport = address_pipe

If this syntax will not work, is there an additional way to include a
secondary aliases file?

The reason I am asking for this is because one alias file is modified by
hand, but the other one is automatically generated.

Thanks!

Jason.
