No, I'm not confusing the two. My point is that running a mail relay
(which implies both incoming and outgoing SMTP) from a dynamic address
range is going to limit the functionality of your mail server because
your server will be blacklisted by subnet block. If you are running an
incoming mail server only then you are essentially breaking the
protocol if you cannot reliably return bounced messages, for example.
