Sorry, it is my mistake since i didn't ask my question correctly. What i meant to ask, is how many outbound processes to remote email servers can postfix handle simultaneously (in case sending emails to many different remove hosts and not 1 specific host) I understand that in case send to 1 host , then transport_destination_concurrency_limit will apply. But my question is that incase postfix is to send to 200 different remote smtpd hosts simultaneously , then how many outbound process postfix can handle simultaneously as default ? and how to increase its value ? Many thanks again. Peter Michael
