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.
- -j
- Respond to the message regardless of whether the login is
listed as a recipient for the message. Do not use this flag unless you are
sure of the consequences. For example, this will cause to reply to mailing
list messages which may result in removing you from the list.
- -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 returnaddr
- Set the reply envelope sender address
- -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>.
