Suddenly shutdown delayed -

[Bob Goodwin]

        For the last several days shutdown of this F-15 computer has
        developed a delay.

        When I click on shutdown it immediately switches to a black
        screen with one line at the top:

             sendmail " some numbers I couldn't copy" unqualified host
        name [box9] unknown   sleeping for retry

        There were some punctuation marks I left out too.

        I don't know what I might have done to trigger this but it is
        annoying since shutdown stops for what seems like a minute
        before going through the normal process that I am accustomed to
        seeing.

        Where does it get this qualified host name from? What do I need
        to fix or am I stuck until I install F-16 which I have been
        putting off?
