    If you have SMTP relaying turned on, turn it off.

    Do you have a <FORM> command on your webpage?

    Two things to do...turn off SMTP relaying (if you can). Run a virus scanner on the email server to see if you have been "infected."

    ok guys ... i can't turn off the SMTP coz' the mail goes through it ...
    the server act as in-comming and out-going mail server ... and it's just a mail server not web based mail system.

    so how can i deny SMTP mail relaying from outside my LAN.
    and by the way ... anti virus didn't help .

    Bimmer, You should get a firewall. Have it filter all out going data packets port 25(SMTP).
    Specify that you only want outbound traffic on your smtp coming from your lan.

    I asked a few co-workers about this and they could offer any other FOR SURE solution. The Best way would be a software firewall. Configure it filter 25,and set the rule. Other than that theorectically, I think you could download a Administration tool from any Networking site. I'm sure somone has made a program doing what you need.

    I am interested in how your being exploited. Do you have a website? If that has a mail server on it. And you use your mail server to submit <FORM> in HTML you could be exploited in more ways than one.

    Are you using "Send Mail" as you SMTP Engine? If not, what are you using?
