getmail_mbox(1) 						   User Commands						   getmail_mbox(1)

NAME
getmail_mbox - read a message from stdin and deliver to a named mboxrd-format mbox file with fcntl-style locking. SYNOPSIS
getmail_mbox [OPTION] PATH DESCRIPTION
Deliver a mail message from standard input, to the mboxrd-format mbox file named PATH. PATH must start with a dot or a slash and must not end with a slash. fcntl-type locking is used; if your system requires another type of locking (such as flock or dotlock ), use an MDA con- figured for that style of locking instead. getmail_mbox uses the SENDER environment variable to construct a Return-Path: header field and the contents of the RECIPIENT environment variable to construct a Delivered-To: header field at the top of the message. SENDER is also used in creating the mbox From_ line. --verbose, -v print a status message on success AUTHOR
