NAME

     vacation -- return ``I am not here'' indication

SYNOPSIS

     vacation -i [-r interval]
     vacation -l
     vacation -x
     vacation [-a alias] [-d] [-f db] [-m msg] [-j] [-z] login

DESCRIPTION

     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''.

     Available options:

     -a alias
             Handle messages for alias in the same manner as those received
             for the user's login name.

     -d      Print messages to stderr instead of syslog.

     -f db   Uses db as the database file.

     -m msg  Uses msg as the message file.

     -j      Reply to the message even if our address cannot be found in the
             ``To:'' or ``Cc:'' headers.  This option is very dangerous and
             should be used with extreme care.

     -z      Set the envelope sender of the reply message to ``<>''.

     -i      Initialize the vacation database files.  It should be used before
             you modify your .forward file.

     -r      Set the reply interval to interval days.  The default 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'' loops.

     -x      Reads a list of addresses from standard input, one per line, and
             adds them to the vacation database.  Mail coming from these
             excluded addresses will not get a reply.  Whole domains can be
             excluded using the syntax ``@domain''.

     -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.

     When started without arguments, vacation will guide the user through the
     configuration process.

     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
     insensitive) 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).  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
           Precedence: bulk

           I am on vacation until July 22.  If you have something urgent,
           please contact Keith Bostic <bostic@CS.Berkeley.EDU>.
           --eric

     Any occurrence of the string $SUBJECT in .vacation.msg will be replaced
     by the subject of the message that triggered the vacation program.

     vacation reads the incoming message from standard input, checking the
     message headers for either the UNIX ``From'' line or a ``Return-Path''
     header to determine the sender.  If both are present the sender from the
     ``Return-Path'' header is used.  Sendmail(8) includes this ``From'' line
     automatically.

     Fatal errors, such as calling vacation with incorrect arguments, or with
     non-existent logins, are logged on the standard error output and in the
     system log file, using syslog(3).

DIAGNOSTICS

     The vacation utility exits 0 on success, and >0 if an error occurs.
