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 -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. -.It Fl d -Enable debugging mode. -See below. -.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 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 -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 -or -.Dq Precedence: junk -line is included in the mail headers. -The people who have sent you messages are maintained as a -.Xr hash 3 -database in the file -.Pa .vacation.db -in your home directory. -.Pp -.Nm Vacation -expects a file -.Pa .vacation.msg , -in your home directory, containing a message to be sent back to each -sender.
