Some of us don't have a choice and are stuck with MS mail products due to work

I posted about the List-ID changing three days ago, but it seems to have gotten

Howdy! I'm trying to figure out some tuning for a cluster of postfix servers
behind a load balancer. The load balancer simply does a round-robin of 4
nodes, direct TCP passthrough and does not mangle the traffic in any way. We

We are setting up Postfix to be an on-premise mail lookup and forward service
