This version also ignores the From header. Features in the AIX 4.3 version: /usr/share/lib/vacation.def interval set with -f (like -t in solaris, with unit) Features in the DU version: /usr/share/lib/vacation.def interval can't be set (1 week) Features in the HP-UX 10.20 version: /usr/share/lib/vacation.def interval can't be set (1 week) Features in the IRIX version (a very old BSD port): interval set with -r (in days?) Features in the Solaris version: /etc/mail/vacation.def (used in the automatical installation process) interval set with -t (with unit) installation procedure http://www.FreeBSD.org/cgi/cvsweb.cgi/src/usr.bin/vacation/?cvsroot=freebsd http://www.FreeBSD.org/cgi/cvsweb.cgi/basesrc/usr.bin/vacation/?cvsroot=netbsd http://www.FreeBSD.org/cgi/cvsweb.cgi/src/usr.bin/vacation/?cvsroot=openbsd vacation-3.3.1/vacation.10000644000000000000000000001460112421776730012111 0ustar .\" $NetBSD: vacation.1,v 1.11 1999/08/17 03:36:36 enami Exp $ .\" .\" Copyright (c) 1985, 1987, 1990, 1991, 1993 .\" The Regents of the University of California.

The intended use is in a .Pa .forward file. For example, your .Pa .forward file might have: .Bd -literal -offset indent \eeric, "|/usr/bin/vacation -a allman eric" .Ed .Pp which would send messages to you (assuming your login name was eric) and reply to any messages for .Dq eric or .Dq allman . .Pp Available options: .Bl -tag -width Ds .It Fl a Ar alias Handle messages for .Ar alias in the same manner as those received for the user's login name. Using .Fl a .Pa alias multiple times is possible. .It Fl c Ar ccaddr Copy the vacation messages to .Ar ccaddr . .It Fl d Print messages to stderr instead of syslog. .It Fl f Ar db Uses .Ar db as the database file. .It Fl m Ar msg Uses .Ar msg as the message file. .It Fl j Reply to the message even if our address cannot be found in the .Dq To: or .Dq Cc: headers. This option is very dangerous and should be used with extreme care. .It Fl z Set the envelope sender of the reply message to .Dq <> . .It Fl i Initialize the vacation database files. It should be used before you modify your .Pa .forward file. .It Fl r Set the reply interval to .Ar interval days. The default is one week. An interval of .Dq 0 means that a reply is sent to each message, and an interval of .Dq Li infinite (actually, any non-numeric character) will never send more than one reply. It should be noted that intervals of .Dq Li \&0 are quite dangerous, as it allows mailers to get into .Dq I am on vacation loops. .It Fl 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 .Dq @domain . .It Fl 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. .El .Pp When started without arguments, .Nm will guide the user through the configuration process. .Pp No message will be sent unless .Ar login (or an .Ar alias supplied using the .Fl a option) is part of either the .Dq To: or .Dq Cc: headers of the mail. No messages from .Dq ???-REQUEST , .Dq Postmaster , .Dq Tn UUCP , .Dq MAILER , or .Dq MAILER-DAEMON will be replied to (where these strings are case insensitive) nor is a notification sent if a .Dq Precedence: bulk , .Dq Precedence: list , .Dq Precedence: junk , .Dq X-Spam-Flag: yes or .Dq Auto-submitted: (something other than no) line is included in the mail headers. The people who have sent you messages are maintained as a .Xr db 3 database in the file .Pa .vacation.db in your home directory. .Pp .Nm expects a file .Pa .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: .Pp .Bd -unfilled -offset indent -compact 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 . --eric .Ed .Pp Any occurrence of the string .Li $SUBJECT in .Pa .vacation.msg will be replaced by the subject of the message that triggered the .Nm program. .Pp .Nm reads the incoming message from standard input, checking the message headers for either the .Ux .Dq From line or a .Dq Return-Path header to determine the sender. If both are present the sender from the .Dq Return-Path header is used. .Xr Sendmail 8 includes this .Dq From line automatically. .Pp Fatal errors, such as calling .Nm with incorrect arguments, or with non-existent .Ar login Ns Ar s , are logged on the standard error output and in the system log file, using .Xr syslog 3 . .Sh DIAGNOSTICS The .Nm utility exits 0 on success, and >0 if an error occurs. .Sh FILES .Bl -tag -width "vacation.dirxxx" -compact .It Pa ~/.vacation.db database file .It Pa ~/.vacation.msg message to send .It Pa ~/.forward .El .Sh SEE ALSO .Xr aliases 5 , .Xr sendmail 8 , .Xr syslogd 8 .Sh HISTORY The .Nm command appeared in .Bx 4.3 . .Sh AUTHOR .Nm was developed by Eric Allman and the University of California, Berkeley in 1983. .br This version is maintained by Marco d'Itri and contains code taken from the three free BSD and some patches applied to a linux port. vacation-3.3.1/Makefile0000644000000000000000000000044212421301342011640 0ustar LIBS=-ldb CFLAGS=-DHAVE_PATHS_H $(shell dpkg-buildflags --get CFLAGS) LDFLAGS=$(shell dpkg-buildflags --get LDFLAGS) all: vacation vacation: vacation.c $(CC) $(CFLAGS) $(LDFLAGS) $(LIBS) $< -o $@ distclean: clean clean: -rm -f vacation install: cp vacation debian/vacation/usr/bin/ vacation-3.3.1/build0000644000000000000000000000000012421276605011225 0ustar vacation-3.3.1/debian/0000755000000000000000000000000012421777035011442 5ustar vacation-3.3.1/debian/control0000644000000000000000000000121612421276771013046 0ustar Source: vacation Section: mail Priority: extra Maintainer: Phil Brooke Uploaders: Ian Jackson Build-Depends: debhelper (>= 9.0), libdb-dev (>= 5.1) Standards-Version: 3.9.6 Package: vacation Architecture: any Depends: ${shlibs:Depends}, ${misc:Depends} Replaces: bsdmainutils (<= 4.8) Conflicts: bsdmainutils (<= 4.8) Description: email autoresponder Vacation returns a message to the sender of a message telling them that you are currently not reading your mail. .
