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.
