— email forwarding information
Users may put a .forward
file in their home directory. If this
file exists, smtpd(8)
forwards email to the
destinations specified therein.
file contains a list of expansion values, as
described in aliases(5)
. Each expansion
value should be on a line by itself. However, the .forward
mechanism differs from the aliases mechanism in that it disallows file
inclusion (:include:) and it performs expansion under the user ID of the
Permissions on the .forward
file are very strict and expansion
is rejected if the file is group or world-writable; if the home directory is
group writeable; or if the file is not owned by the user.
Users should avoid editing directly the .forward
prevent delivery failures from occurring if a message arrives while the file
is not fully written. The best option is to use a temporary file and use the
command to atomically overwrite the
. Alternatively, setting the
bit on the home directory will
cause the .forward
lookup to return a temporary failure,
causing mails to be deferred.
