<header>Disable kernel file lock on mailboxes</header>

<hr>

This parameter disables kernel file locks on mailboxes.

<p>

This is needed on SUN workstations because the <tt>mailtool</tt> program keeps
an exclusive kernel lock while its window is open. SUN software uses
<tt>user.lock</tt> files only. Unless you remove all SUN mail software, kernel
locks just give a false sense of security.
