What dyndns service *exactly* are you using? Further, what *exactly* are
you trying to achieve?

How is the machine connected to the internet? Is it a VPS/dedicated
server with a direct connection, or is it sitting behind your
home/office router? If the latter, you'll need router-side configuration
to get connections through.

Good start...

You don't understand *all* or *any*? If the former, which? If the
latter, it is probably worth going back a few steps to be sure that
running a mailserver is really a good solution to the problem you are
trying to solve. It isn't to be undertaken lightly.

This is far too dependent on the purpose. Please explain what you're
trying to do!

In this context, what are your "main computer" and "server" - and which,
if any, is the Lenny box?
Does the question roughly equate to "How do I set up an IMAP server" or
"How do I use a smarthost and fetchmail to proxy a mailbox"?
