forward — email
forwarding information file
Users may put a
.forward file in their
home directory. If this file exists, smtpd(8) forwards
email to the destinations specified therein.
.forward 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
Users should avoid editing directly the
.forward file to 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 mv(1)
command to atomically overwrite the former
Alternatively, setting the sticky(8) bit on the home
directory will cause the
.forward lookup to return a
temporary failure, causing mails to be deferred.

The following file forwards mail to “email@example.com”, and pipes the same mail to “examplemda”.
# empty lines are ignored firstname.lastname@example.org # anything after # is ignored "|/path/to/examplemda"
