except that there has been quite some relay attempts (and spam) from China (mostly), throughout the whole month. faking to be a grootersnet.nl user, it will never be accepted when sent to another address since the mail server is set to be non-relay. At least, not from the outside. And grootersnet.nl mail will only be sent from the inside over DIANA, the main (OpenVMS) server.
But it does cause trouble because each message prevents the anti-spam program from receiving valid mail – so the most used networks have been excluded at the front gate (so the router) so they will have no longer access to ANY service:

  • 112.88.0.0/13
  • 157.122.0.0/16
  • 5.196.0.0/16
  • 125.21.122.0/24
  • More to follow – after I have examined all log files of mail, web , ftp and router.
    For the rest, all seems pretty well.
