NAME

       mlock -- lock a mailbox

SYNOPSIS

       /usr/bin/mlock

DESCRIPTION

       If libc-client.so is unable to create a mailbox lock file, it will call this program.  This makes using
       the mailbox safe over i.e. NFS. There is no reason to call mlock yourself or through another program.  It
       is setgid mail so there is no need to change the permissions of /var/mail to 1777.

BUGS

       No documentation other than this crappy man page,
