This is bizarre.  What's happening has nothing to do with the
recipient.  Probably either vuw.ac.nz, but more likely ecosse.net
itself, is refusing your unverifiable, unlisted `flux.localdomain'
address.  I believe this is a violation of RFC 1123.  (If you accept
an SMTP connection, you're not supposed to worry about anything but
whether the final address is deliverable at the next hop; in
particular, you MUST NOT refuse mail because the HELO is bad.  I'm not
sure this extends to the envelope return address and/or Return-Path,
though.)

I take it you don't dialup directly into ecosse?

What you need to do is to convince qmail to masquerade your `baz' user
as TheEnglishman [at] ecosse.net.  You may also want to consider finding an
alternative ISP.  (Eg, relay through planet instead of ecosse.)

A little testing at ecosse convinces me you really don't want to hang
around there....
