If I understand this, you have a mail server using your ISP's
mail server as its smarthost.  However, your client machine
is not configured to use a smarthost.  I would suggest that
you configure your client machine to use your mail server as
a smarthost, since that will make it easier to troubleshoot
problems and will give you one point where all outbound email
is queued when your connections is down.
