Wishful thinking. Nobody does that by default.

Looking at their site, it _seems_ that with no-ip free you can not just
have an A record but even up to three MX records. So you'll want to add
a MX record to point to your IP, then your portforwarder there can pick
up incoming mail and deliver it to your NATed mailbox.
You might want to get a friend to do backup-MX for you though. Something
like someone else with a no-ip free account who also wants mail on his
own machine on a ``I scratch your back, you scratch mine'' basis.
