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"
Available options:
-aalias- 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 stdout.
-fdatabase_file- Use the specified database_file prefix and append
.dbto it instead of$HOME/.vacation.db. -FF|R|S- Make
vacationadditionally look in From: (F), Return-Path: (R), or Sender: (S) headers to determine the From: field. -i-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:orCc:lines. Usage of this option is strongly discouraged because it will result invacationreplying to mailing lists or other inappropriate places (e.g., messages that you have beenBccto). -mmessage_file- Use message_file instead of
$HOME/.vacation.msg. -ssender- Reply to sender instead of the value read from the message.
-rinterval-tinterval- Set the reply interval to interval days. If the
interval number is followed by
w,d,h,m, orsthen 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” loops. -TA|D- Make
vacationadditionally look in Apparently-To: (A) or Delivered-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 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). If the message contains the string
$SUBJECT then it will will be replaced with the
subject of the original message. For example, it might contain:
From: eric@CS.Berkeley.EDU (Eric Allman) Subject: I am on vacation Delivered-By-The-Graces-Of: The Vacation program Precedence: bulk I am on vacation until July 22. Your mail regarding "$SUBJECT" will be read when I return. If you have something urgent, please contact Keith Bostic <bostic@CS.Berkeley.EDU>. --eric
vacation reads the first line from the
standard input for a UNIX “From” line
to determine the sender.
sendmail(1) includes this “From” line
automatically.
Fatal errors, such as calling vacation
with incorrect arguments, or with non-existent
logins, are logged in the system
log file, using
syslog(3).

BUGS
Adding -T A or
-T D should only be done for
misconfigured or non-compliant MTAs. Doing so may auto-respond to messages
that were not supposed to be replied to.
