So if you can send a mail to test-admin at remco.homeip.net as some
user, but the mailman scripts cannot, I have no idea what the problem
might be.  It must be some very strange error in sendmail depending
on some sender context, and reporting the error wrongly, or else
some subtle error in the SMTP dialogue.  I'd
probably watch the SMTP session with truss/strace/ktrace or
whatever and see exactly what Mailman is sending, and duplicate
that with a telnet to port 25.
