Files referenced using the :include:
syntax
have the same syntax as ~/.forward files.
Any files written via a :include:
file
must be writable by the owner of the :include:
file,
and any other :include:
files referenced for inclusion
must be readable by the owner of the referencing
:include:
file.
To set up a mailing list managed by, for example, sally, set up the following aliases:
sample: :include:/var/lists/sample.list sample-request: sally owner-sample: sample-request
Then create the file /var/lists/sample.list, mode 644, and owned by sally. Mail sent to sample will be sent to everyone on the list. Error messages will go directly to sample-request, and in turn to sally. (The list-request syntax is an Internet convention, see §25.2.)
