I have this resolved now (I'm now writing to the list from mail on said server,
over imap with mutt at home).
I figured this out, sort of, before your message, but what I did makes more sense now.
I did see "sendmail" listening on port 25 (lsof -i :25), but didn't have sendmail installed,
which was confusing (exim4 was on by default, but removed when I installed postfix,
but sendmail?), but I killed -9 the pid for sendmail and restarted postfix.
Then lsof -i :25 showed "master" listening on that port, as you say.
And now all seems to be working as it should (or as I expected it should).

Yes. It is hosting websites, a gopher site, and, now, e-mail.
