On a side note, I was maybe little bit too fast when I said they are not
RFC compliant. Maybe they just have some kind of bounce verification,
and only "signed" return-paths are accepted. However, their don't even
accept EHLO, which is a requirement for "recent" mail servers (but they
probably have a Cisco PIX with ""fixup""-smtp-protocol activated).
