Hi guys, I have a question for you all. In my work we have a few ispconfig 3 servers, running on lenny in production, some times, as many of you lived I'm sure, we have a user who use as password "qwerty" or "123456" and a evil man cracked and use it to send a bunch off garbage, causing a big trouble (mass use of resources, grey listing, etc). There is any way to limit the number of mails a user can send in a period of time? like... 100 mail per hour. Thanks a lot guys, I dont know what to do without you.
