Unless you have a webserver that returns "custom" errorpages as normal html
documents (return code 200) instead of a 'real' 404 message.

I found this in 2 machines in indian ip block. My another server at US
is not affected by this. Some one else seeing this? Could this be the
next wave of spam ??

  Some people are using your apache as mailrelay. Did you enable
  proxying? Getting a "200" indicates that the connect to those
  mailservers was successful. Make sure that you configure your
  apache not to accept CONNECTs from everywhere to other than
  special ports, if you need proxying at all (if you don't need
  it disable that feature).
  I see people trying to connect to other servers each day, but
  they get an "405" error.

  Cheers,



                                                          Chris.
