Forms of Alias Delivery
Addresses in the righthand side of an alias entry can take four forms:
LHS: user LHS: /file LHS: |program LHS: :include: file
The user specifies final delivery
to a user’s mail spool file (subject to change by the user’s
~/.forward file), or delivery
to a new address (e.g., newuser or
user@newsite). The
/file specifies delivery
by appending to a file. The |program
specifies delivery by piping the message through a program.
The :include: specifies
processing of a mailing list. The first three are covered
here. The last is covered in the next chapter.
These righthand sides can be combined on a single line, where one is separated from another by a comma. For example:
LHS: user,/file
