Exim tells me "no immediate delivery: more than 30 messages received in one connection"
The emails then sit in the exim queue until a queue runner kicks in - which happens once every 30 minutes. The result is considerable delays which makes list email conversations bouncy.
Question: how do I tell MM3 to send no more than 30 emails in one connection to exim (via SMTP to localhost port 25) ?
If that is not possible, how do I find the number that MM3 batches outgoing emails so that I can configure exim to match (as I did with MM2) ?
I see documentation pages like the following. They are useless to me, incomprehensible without a lot of learning. I program in several languages but only a little Python. What I am looking for is a setting in a config file.
