  FYI: The last few days I've seen repeated relay attempts using my own
e-mail address as "from", probably in the hope that the server would be
fooled by seeing its own domain. See below.

becomes widespread.

  So far I've seen it only from a single IP (213.26.134.163, so there
<g>), each time with different HELO and RCPT TO data. It's an Italian
IP, so it should come as no surprise that this keeps going on despite me
reporting the first three attempts to .
