Hi Matthew, Hi Wietse, Our postfix servers are only MTAs who transfer mails from internal IT apps to end users over Internet. We don't receive mails from Internet.
Sometimes, an abnormal activity can fill active queue unitl it's full, and it slow down all mail delivery. We had some rules to slow down delivery to specif destination, some other to send mail more quickly for others, and remains with default smtp delivery configuration. I was wondering if we can rate limit connections to Postfix to reject mails if active queue are full (I know postfix can accept mail to incoming queue when active queue is full), when a client send a unusual number of messages.
