41 .Nd mail forwarding instructions
45 file contains a list of mail addresses or programs
46 that the user's mail should be redirected to.
48 file is not present, then no mail forwarding will be done.
49 Mail may also be forwarded as the standard input to a program
51 with the normal shell pipe symbol (|).
53 are to be passed to the command, then the entire line
54 should be enclosed in quotes.
55 For security reasons, the
57 file must be owned by the user the mail is being sent to,
58 or by root, and the user's shell must be listed in
63 file contained the following lines:
64 .Bd -literal -offset indent
66 "|/usr/bin/vacation nobody"
69 Mail would be forwarded to
70 .Aq nobody@FreeBSD.org
73 with the single argument
76 If a local user address is prefixed with a backslash
77 character, mail is delivered directly to the user's
78 mail spool file, bypassing further redirection.
80 For example, if user chris had a
82 file containing the following lines:
83 .Bd -literal -offset indent
88 One copy of mail would be forwarded to
90 and another copy would be retained as mail for local user chris.
92 .Bl -tag -width $HOME/.forward -compact
94 The user's forwarding instructions.
