VACATION

NAME

vacation - E-mail auto-responder

SYNOPSIS

vacation [-a alias] [-C cffile] [-d] [-f database] [-i] [-I] [-l] [-m message] [-r interval] [-s address] [-t time] [-U] [-x] [-z] login

DESCRIPTION

Vacation returns a message, ~/.vacation.msg by default, to the sender informing them that you are currently not reading your mail. The message is only sent to each sender once per reply interval (see -r below). 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.
-C cfpath: Specify pathname of the sendmail configuration file. This option is ignored if -U is specified. This option defaults to the standard sendmail configuration file, located at /etc/mail/sendmail.cf on most systems.
-d: Send error/debug messages to stderr instead of syslog. Otherwise, fatal errors, such as calling vacation with incorrect arguments, or with non-existent logins, are logged in the system log file, using syslog(8). This should only be used on the command line, not in your .forward file.
-f filename: Use filename as name of the database instead of ~/.vacation.db or ~/.vacation.{dir,pag}. Unless the filename starts with / it is relative to ~.
-i: Initialize the vacation database files. It should be used before you modify your .forward file. This should only be used on the command line, not in your .forward file.
-I: Same as -i (for backwards compatibility). This should only be used on the command line, not in your .forward file.
-l: List the content of the vacation database file including the address and the associated time of the last auto-response to that address. This should only be used on the command line, not in your .forward file.
-m filename: Use filename as name of the file containing the message to send instead of ~/.vacation.msg. Unless the filename starts with / it is relative to ~.
-r interval: Set the reply interval to interval days. The default is one week. An interval of ``0'' or ``infinite'' (actually, any non-numeric character) will never send more than one reply. The -r option should only be used when the vacation database is initialized (see -i above).
-s address: Use address instead of the incoming message sender address on the From line as the recipient for the vacation message.
-t time: Ignored, available only for compatibility with Sun's vacation program.
-U: Do not attempt to lookup login in the password file. The -f and -m options must be used to specify the database and message file since there is no home directory for the default settings for these options.
-x: Reads an exclusion list from stdin (one address per line). Mails coming from an address in this exclusion list won't get a reply by vacation. It is possible to exclude complete domains by specifying ``@domain'' as element of the exclusion list. This should only be used on the command line, not in your .forward file.
-z: Set the sender of the vacation message to ``<>'' instead of the user. This probably violates the RFCs since vacation messages are not required by a standards-track RFC to have a null reverse-path.

Vacation reads the first line from the standard input for a UNIX ``From'' line to determine the sender. Sendmail(8) includes this ``From'' line automatically.

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'', ``???-RELAY'', ``???-OWNER'', ``OWNER-???'', ``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'' or ``Precedence: junk'' line is included in the mail headers. The people who have sent you messages are maintained as a db(3) or dbm(3) database in the file .vacation.db or .vacation.{dir,pag} 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
