The vacation command expects a $HOME/.vacation.msg file containing a message to be sent back to each sender. If this file does not exist, the vacation command looks for /usr/share/lib/vacation.def, a systemwide default vacation message file. It should be an entire message, including any desired headers, such as From or Subject. By default, this message is sent only once a week to each person who sends mail to you. Use the -f flag to change the frequency intervals at which the message is sent. The names of the people who send messages are kept in the files $HOME/.vacation.pag and $HOME/.vacation.dir. These files are created when the vacation command is initialized for your user ID using the -I (uppercase i) flag.
If the -I flag is not specified, the vacation command reads the first line from the standard input for a From line to determine the sender. If no text is available from standard input, the command returns an error message. All properly formatted incoming mail should have a From line. No message is sent if the From header line indicates that the message is from Postmaster, MAILER-DAEMON, or if the initial From line includes the string-REQUEST@ or if a Precedence: bulk or Precedence: junk line is included in the header.

statement in the .forward file:
The sender receives the message that is in the $HOME/.vacation.msg file, or if the file does not exist, the default message found in the /usr/share/lib/vacation.def file. If neither of these files exist, no automatic replies are sent to the sender of the mail message and no error message is generated. If either of these files exist, the sender receives one vacation message from mark per week, regardless of how many messages are sent to mark from the sender.
- If the following entry is
contained in your .forward file,
The sender receives one vacation message from mark every ten days, regardless of how many messages are sent to mark from the sender.
mark, |"/usr/bin/vacation -f10d mark"
