I don't understand: why is your smtp server identing me?

Ah, I see. For what purpose is such a list available?

Fortunately, I don't have to deal with that, ;-). Would it be wise to
setup a smart host on my server to deal with mail sent by my workstation?
That way I could probably send mail even if my connection was failing
without my workstation complaining all over the place and the mail would
be send after my connection came back up. Do I have this right?
