    Wow its been a while :p

    Anyway, I am trying to get Postfix with ISPC to deny all client AUTH requests. I don't want my clients to use the ISPC server to send mail from. I'm worried that one of them will send 100000 emails and the server might get blacklisted for spam, and I don't want that tremendous CPU load on the server as well.

    I have tried to disable sasl, but then the server seems to relay for anyone on the net without authentication. :/

    I also tried the options:
    mynetworks_style = host
    relay_domains =

    But it doesnt make a difference. Any help here would be great.

    Disable SASL and run
    postconf -e 'mynetworks ='
