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:
-a
alias-d-f
database_file.db to it instead of
$HOME/.vacation.db.-F
F|R|Svacation additionally look in From: (F),
Return-Path: (R), or Sender: (S) headers to determine the From:
field.-i-I-jTo: or Cc: lines. Usage of
this option is strongly discouraged because it will result in
vacation replying to mailing lists or other
inappropriate places (e.g., messages that you have been
Bcc to).-m
message_file$HOME/.vacation.msg.-s
sender-r
interval-t
intervalw, 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” loops.-T
A|Dvacation additionally 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).
No notification is sent if a “Precedence: bulk”
“Precedence: list” “Precedence: junk” line or an
“Auto-Submitted:” line with any qualifier except
“no” are included in the mail headers.
vacation will include these headers in its response
to avoid auto-responder loops.
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 <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).
RFC 2076 , RFC 3834
vacation command appeared in
4.3BSD.
-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.
