    Is there a way to monitor smtp / postfix usage such that if a spammer/bot gets access to a maibox credential you are:

    1. Aware as soon as there's a surge in smtp usage compared to average
    2. Can take action (like disabling the account)
    Ideally if it can email a daily report and an immediate report when use is above average.
    I'm using ISBConfig 3 on Ubuntu

    You can monitor your mail-queue with a small script. I would not let a script disable an account. But if you have to many mails in your queue (the value is up to you), you can let the script send you a mail so you can check the server yourself.
    Tun Lin Aung and Airbag888 like this.

    Thank you for your reply florian.. Could you point me in the right direction to learn how to do such a script? I'd likely configure it to use an external smtp server (gmail?) since ours would likely be flooded at that point, maybe even blacklisted
