Postfix default settings are carefully chosen and should give reliable performance under a wide range of loads and conditions. Don't change any of the delivery, scheduling, or queueing defaults unless you have a specific problem to solve. > > My Mailman server is connected to one of my mail gateways > responsible for forwarding messages to the client from the internet. > As I see in the logs Postfix from Mailman server sending each > message with multiple recipients inside. Is this correct or I need > to change here something ? Yes, this is correct. Multiple recipients per message reduces the load on all servers involved. Don't change this unless you have specific problem destinations. See the postfix documentation. > > I`m not 100% sure if each server will accept messages with some many > recipients inside.

People with experience have written postfix and its documentation. If you have a specific problem, see the postfix docs. Specifically, see the "Problem Solving" section of http://www.postfix.org/documentation.html -- Noel Jones
