If the 46file is not present, then no mail forwarding will be done. 47Mail may also be forwarded as the standard input to a program 48by prefixing the line 49with the normal shell pipe symbol (|). If arguments 50are to be passed to the command, then the entire line 51should be enclosed in quotes. For security reasons, the 52.Nm .forward 53file must be owned by the user the mail is being sent to, 54or by root, and the user's shell must be listed in 55.Pa /etc/shells . 56.Pp 57For example, if a 58.Nm .forward 59file contained the following lines: 60.Bd -literal -offset indent 61nobody@FreeBSD.org 62"|/usr/bin/vacation nobody" 63.Ed 64.Pp 65Mail would be forwarded to 66.Aq nobody@FreeBSD.org 67and to the program 68.Pa /usr/bin/vacation 69with the single argument 70.Ar nobody . 71.Pp 72If a local user address is prefixed with a backslash 73character, mail is delivered directly to the user's 74mail spool file, bypassing further redirection. 75.Pp 76For example, if user chris had a 77.Nm .forward 78file containing the following lines: 79.Bd -literal -offset indent 80chris@otherhost 81\echris 82.Ed 83.Pp 84One copy of mail would be forwarded to 85.Ar chris@otherhost 86and another copy would be retained as mail for local user chris. 87.Sh FILES 88.Bl -tag -width $HOME/.forward -compact 89.It Pa $HOME/.forward 90The user's forwarding instructions. 91.El 92.Sh SEE ALSO 93.Xr aliases 5 , 94.Xr mailaddr 7 , 95.Xr sendmail 8 96
