    Hi,
    I just had a problem with a user that was sending 10000 emails via his Outlook at once and for me there was no way to stop it until they complained that Gmail just blocked him. Interestingly enough he didn't end up in any blacklist.

    I suppose this is becoming bigger and bigger problem for everyone out there - the bottom of this is being aware or stop the emails to be sent out at first so all these topics could be avoided:

    Can you guys recommend some tool with step by step tutorial that is easy to implement on top?

    I would need either limiting emails sent per domain or per mailbox or at least some sort of notification when a domain and/or mailbox goes above certain threshold, now it's really a "free for all".

    Any help is very much appreciated.

    I implemented something like that a few years ago by using policyd (cluebringer), but there are other, and hopefully easier to install solutions, that are able to do the same thing. e.g. postfwd. I don't have a tutorial on that topic available.

    there are several solutions, just recently I did mention one ... which I forgot already, but it was hosting on a known site hosting some other postfix tools aswell meh, maybe I remember later - but for now

    I will try that. If you would still remember the "sure working solution" I would greatly appreciate it.

    Thank you!
