Joerg, 1blu is a German ISP where I have rented:

- a domain 'unixare.de'
- a web space www.unixarea.de on some of its servers
- a mail addr guru at unixarea.de which ends up in mbox on its servers and I can
  read mail with IMAP or some webmail software; and I can send mail with
  SMTP to one its MTA (smt.1blu.de)
- SSH access to an unpriv account on the server to put/get files to/from
  the web space www.unixarea.de

I have no access to any DNS configurations and so I do not see how to
follow your hints.

Thanks anyway
