I'd suggest that you use exim and use your isp's mail server as a smarthost. When you install exim, the debconf questions will give you this choice. You'll need the hostname of your isp's smarthost. Local mail will be delivered locally, non-local mail will be sent to the smarthost (with address rewriting so that it appears to the receiver as coming from your public mail name (e.g. h...@example.com, rather than h...@myhome). If you want to receive public mail, you'd use something like fetchmail.
Unless you're running a firewall, you'll already have port 25 (all ports) open. Installing an MTA will simply provide a server listening to port 25. However, with the standard debconf smarthost, I don't think it actually will be listening on your public IP, only on your localnet. I'd further suggest that you install the doc-linux-howto (something like that) package, probably in html format. You'll find lots of info, including mail admin howto.
