Right, this seems to be it. I can telnet to my ISP's mail server on port 25,
but not to any external mail server. If I set up Exim4 to send mail directly
via SMTP, I can't send mail, period. If I set it up to use my ISP as a
smarthost, I can send mail directy from the server using Exim, but can't use
it for mail from within the network or (the only reason I needed the mail
server in the first place) to run a couple of mailman lists.

I have asked; my ISP actually makes a point of saying "you can run servers",
but there may be more details in the fine print....
