    Your server is being used as spammer relay.. Check Your server configuration...

    Make sure smtp/run --> has line which check tcp.smtp.cdb files for host allowed to relay..

    Looks like your server is misconfigured...

    How this can happen..



    1) One or more users passwrod might have got compramized,

    2) Or your server must be configured as open relay.

    2)No proper patch or configuration to deny spamrelay



    How to Stop this from happening.

    1) Edit smtp run file to add relay client check is enabled.

    2) make sure vpopmail purge users who are allowed to relay regularly.

    2) enable rblsmtp check


    Extra.(recompile)


    1) Use chkuser to validate from users.

    2) Use Tarpit patch

    3) Use SMTP greeting Delay.

    4) Use Dns patch..

    Qmail Spam issue

    Thanks You for your reply.
    I am newbie in qmail. I configured the mail server as open relay, if i add some hosts then users will not b able to send the email on any hosts. I want it should be behave like yahoo, hotmail, gmail, user can send and receive mails to any host. and one thing more, how can i check how the spammer has succeeded to send out spam. i have also installed spamassassin. Thanks once again.
