Dear Postfix Experts Thanks to everyone's aid in improving my customer transport settings to the comcast.net domain. Our backlog is going down steadily.
But I'm afraid that despite my efforts to gently spoon feed messages to sensitive domains such as comcast.net, the logs indicate I am still pounding them with messages until we are throttled. Based on my custom transport settings, I would expect that they would only be sent two messages per second because I specify only two concurrent connections to any one domain and messages should be spaced 1 second apart in the custom transport (acct_client1). However, when I look at the logs, it looks like we are send over 50 messages in a 3-second period. Are the logs correct as to the time? If so, how would I correctly slow down the broadcast speed?
