Thanks. I figured out that the "unwanted" open ports were nfs related. I'm not using nfs, so I uninstalled nfs-common and they no longer seem to be open any more.

I assume that I want the 'local address' column to be in the form for most things. I think I can just ignore the 'foreign address' column here?

Unless I'm misreading it horribly, I assume lines like this indicate that the port is listening only on

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

tcp        0      0  *               LISTEN      1322/exim4

For what it's worth, I can telnet to port 25 locally, but not from a remote machine. The open ports were like this:

tcp        0      0 *               LISTEN      836/rpc.statd

(note: that port is no longer open).
