Hi, Our admissions office sends out mass mailings to prospective students, anywhere from 5,000 to 25,000 at a time. They are mail-merged and sent via outlook to the postfix server, one recipient per message. The user reports that outlook sends out 500 messages and then stops. If he restarts outlook, it will send out another 500 and then stop again. If he leaves it overnight, it might send several more thousand by morning. When I look in the mail logs, somewhere around 500 messages, followed by a disconnect. What I don¹t know is whether outlook is disconnecting or whether postfix is closing the connection. Is there a limit, configurable or otherwise, to the number of messages postfix can receive on a single connection? And at that point, does postfix close the connection to the client?
