vacation -- return ``I am not here'' indication
vacation -dIi [-f databasefile] [-m messagefile] [-r interval]
vacation -dj [-a alias] [-F F|R|S] [-f databasefile] [-m messagefile]
[-s sender] [-T A|D] login
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
.forward file. For example, your .forward file might have:
\eric, "|/usr/bin/vacation -a allman eric"
which would send messages to you (assuming your login name was eric) and
reply to any messages for ``eric'' or ``allman''.
Handle messages for alias in the same manner as those received
for the user's login name.
-d Turn debugging on; don't send an actual message, but print it on
Use the specified database_file prefix and append .db to it
instead of $HOME/.vacation.db.
Make vacation additionally look in From: (F), Return-Path: (R),
or Sender: (S) headers to determine the From: field.
-I Initialize the vacation database files. It should be used before
you modify your .forward file.
-j Do not check if the recipient is present in the To: or Cc: lines.
Usage of this option is strongly discouraged because it will
result in vacation replying to mailing lists or other inappropri-
ate places (e.g., messages that you have been Bcc to).
Use message_file instead of $HOME/.vacation.msg.
Reply to sender instead of the value read from the message.
Set the reply interval to interval days. If the interval number
is followed by w, d, h, m, or s then the number is interpreted as
weeks, days, hours, minutes, or seconds respectively. The
default interval is one week. An interval of ``0'' means that a
reply is sent to each message, and an interval of ``infinite''
(actually, any non-numeric character) will never send more than
one reply. It should be noted that intervals of ``0'' are quite
dangerous, as it allows mailers to get into ``I am on vacation''
-T A|D Make vacation additionally look in Apparently-To: (A) or Deliv-
ered-To: (D) headers to determine the To: field.
No message will be sent unless login (or an alias supplied using the -a
option) is part of either the ``To:'' or ``Cc:'' headers of the mail. No
messages from ``???-REQUEST'', ``Postmaster'', ``UUCP'', ``MAILER'', or
``MAILER-DAEMON'' will be replied to (where these strings are case insen-
sitive) nor is a notification sent if a ``Precedence: bulk''
``Precedence: list'' or ``Precedence: junk'' line is included in the mail
headers. The people who have sent you messages are maintained as a db(3)
database in the file .vacation.db in your home directory.
vacation expects a file .vacation.msg, in your home directory, containing
a message to be sent back to each sender. It should be an entire message
(including headers). If the message contains the string $SUBJECT then it
will will be replaced with the subject of the original message. For
example, it might contain:
From: eric@CS.Berkeley.EDU (Eric Allman)
Subject: I am on vacation
Delivered-By-The-Graces-Of: The Vacation program
I am on vacation until July 22.
Your mail regarding "$SUBJECT" will be read when I return.
If you have something urgent, please contact Keith Bostic
vacation reads the first line from the standard input for a UNIX ``From''
line to determine the sender. sendmail(1) includes this ``From'' line
Fatal errors, such as calling vacation with incorrect arguments, or with
non-existent logins, are logged in the system log file, using syslog(3).
~/.vacation.db database file
~/.vacation.msg message to send
The vacation command appeared in 4.3BSD.
Adding -T A or -T D should only be done for misconfigured or non-compli-
ant MTAs. Doing so may auto-respond to messages that were not supposed
to be replied to.
