Hi, 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 Thanks
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.
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
