Betreff: [exim] Bounce Spam problem




    Hi!


    

    I have a serious problem.


    

    Spammers are abusing our system by sending fake bounces to our server,
that Exim 'returns' to the 'sender'.


    

    How can ik ignore, of better, delete before accepting.


    

    I enabled blacklisting. But that fdoes not seem to have any effect.


    

    Cheers,
