Receive Connector Parameters for Ubuntu Postfix
Hello, first of all, please excuse me if my wording is off - I usually have nothing to do with Exchange and Servers in general and never have. We are sending mail from a linux server to a recieve connector via postfix. While sending a larger amount of emails at once (lets say 50 different mails to 50 different adresses at once), we regulary get an error and after a few emails the sending process stops. I looked at the settings of our recieve conncetor and noted the following settings, that may be the source of this problem: MaxInboundConnectionPerSource: 20 MaxInboundConnectionPercentagePerSource: 2 So the questions are: 1. Does Postfix establish multiple Connections at once? If so, would our recieve connector stop recieving mails if Postfix establishes more than 20 connections? 2. If at a single time, only this one system sends mails, thus the Connection Percentage of this one source is at 100%, would our connector stop recieving? Thanks in advance and sorry for the unprofessional language.
