A colleague has just suggested that hamburg have a fire wall
and that the "0" preference is behind it. If this is true, it appears
that sendmail is working its' way through the preferences until it
hits the mail server accessable from outside the firewall, when
it gets the "520" reply, while Postfix is taking it as a hard failure
and stopping.
