This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

.Sh DESCRIPTION
|
|
.Nm Vacation
|
|
returns a message to the sender of a message telling them that you
|
|
are currently not reading your mail. The intended use is in a
|
|
.Pa .forward
|
|
file. For example, your
|
|
.Pa .forward
|
|
file might have:
|
|
.Bd -literal -offset indent
|
|
\eeric, "|/usr/bin/vacation -a allman eric"
|
|
.Ed
|
|
which would send messages to you (assuming your login name was eric) and
|
|
reply to any messages for
|
|
.Dq eric
|
|
or
|
|
.Dq allman .
|
|
.Pp
|
|
Available options:
|
|
.Bl -tag -width Ds
|
|
.It Fl a Ar alias
|
|
Handle messages for
|
|
.Ar alias
|
|
in the same manner as those received for the user's
|
|
login name.
|
|
.It Fl i
|
|
Initialize the vacation database files. It should be used
|
|
before you modify your
|
|
.Pa .forward
|
|
file.
|
|
.It Fl r
|
|
Set the reply interval to
|
|
.Ar interval
|
|
days. The default is one week. An interval of
|
|
.Dq 0
|
|
means that
|
|
a reply is sent to each message, and an interval of
|
|
.Dq Li infinite
|
|
(actually, any non-numeric character) will never send more than
|
|
one reply. It should be noted that intervals of
|
|
.Dq Li \&0
|
|
are quite
|
|
dangerous, as it allows mailers to get into
|
|
.Dq I am on vacation
|
|
loops.
|
|
.It Fl l
|
|
Print the contents of the vacation database files. For each entry,
|
|
the address the reply has been sent to and the associated time will
|
|
be printed to standard output.
|
|
.El
|
|
.Pp
|
|
No message will be sent unless
|
|
.Ar login
|
|
(or an
|
|
.Ar alias
|
|
supplied using the
|
|
.Fl a
|
|
option) is part of either the
|
|
.Dq To:
|
|
or
|
|
.Dq Cc:
|
|
headers of the mail.
|
|
No messages from
|
|
.Dq ???-REQUEST ,
|
|
.Dq Postmaster ,
|
|
.Dq Tn UUCP ,
|
|
.Dq MAILER ,
|
|
or
|
|
.Dq MAILER-DAEMON
|
|
will be replied to (where these strings are
|
|
case insensitive) nor is a notification sent if a
|
|
.Dq Precedence: bulk
|
|
or
|
|
.Dq Precedence: junk
|
|
line is included in the mail headers.
|
|
The people who have sent you messages are maintained as a
|
|
.Xr hash 3
|
|
database in the file
|
|
.Pa .vacation.db
|
|
in your home directory.
|
|
.Pp
|
|
.Nm Vacation
|
|
expects a file
|
|
.Pa .vacation.msg ,
|
|
in your home directory, containing a message to be sent back to each
|
|
sender. It should be an entire message (including headers). For
|
|
example, it might contain:
|
|
.Pp
|
|
.Bd -unfilled -offset indent -compact
