+\fBpostlock\fR [\fB\-c \fIconfig_dir\fR] [\fB\-l \fIlock_style\fR]
+        [\fB\-v\fR] \fIfile command...\fR
+.SH DESCRIPTION
+.ad
+.fi
+The \fBpostlock\fR(1) command locks \fIfile\fR for exclusive
+access, and executes \fIcommand\fR. The locking method is
+compatible with the Postfix UNIX\-style local delivery agent.
+
+Options:
+.IP "\fB\-c \fIconfig_dir\fR"
+Read the \fBmain.cf\fR configuration file in the named directory
+instead of the default configuration directory.
+.IP "\fB\-l \fIlock_style\fR"
+Override the locking method specified via the
+\fBmailbox_delivery_lock\fR configuration parameter (see below).
+.IP \fB\-v\fR
+Enable verbose logging for debugging purposes. Multiple \fB\-v\fR
+options make the software increasingly verbose.
+.PP
+Arguments:
+.IP \fIfile\fR
+A mailbox file. The user should have read/write permission.
+.IP \fIcommand...\fR
+The command to execute while \fIfile\fR is locked for exclusive
+access.  The command is executed directly, i.e. without
+interpretation by a shell command interpreter.
+.SH DIAGNOSTICS
+.ad
+.fi
+The result status is 75 (EX_TEMPFAIL) when \fBpostlock\fR(1)
+could not perform the requested operation.  Otherwise, the
+exit status is the exit status from the command.
+.SH BUGS
+.ad
+.fi
+With remote file systems, the ability to acquire a lock does not
+necessarily eliminate access conflicts. Avoid file access by
+processes running on different machines.

+.IP \fBMAIL_CONFIG\fR
