An abbreviation for 'Hangup' I think.

It probably means that you should do a 'kill -1 {process_id}' because
signal number 1 is:

  Signal     Value     Action   Comment
  -------------------------------------------------------------------------
  SIGHUP        1        A      Hangup detected on controlling terminal
                                or death of controlling process

...yep - I think that's what it means.  That signal will make qmail-send
think that the 'controlling terminal' hung up - so it rereads the config
file and tries again.

I could be way off base here though.  If someone else answers - believe
them instead of me!
