NAME
          qmail-lspawn - schedule local deliveries

     SYNOPSIS
          qmail-lspawn defaultdelivery

     DESCRIPTION
          qmail-lspawn reads a series of local delivery commands from
          descriptor 0, invokes qmail-local to perform the deliveries,
          and prints the results to descriptor 1.  It passes
          defaultdelivery to qmail-local as the default delivery
          instruction.

          qmail-lspawn invokes qmail-local asynchronously, so the
          results may not be in the same order as the commands.

          For each recipient address, qmail-lspawn finds out which
          local user controls that address.  It first checks the
          qmail-users mechanism; if the address is not listed there,
          it invokes qmail-getpw.  qmail-lspawn then runs qmail-local
          under the user's uid and gid.  It does not set up any
          supplementary groups.

          qmail-lspawn treats an empty mailbox name as a trash
          address.
