Hi, Thanks for the tip, but my problem isn’t with deferred mail, no mail is getting rejected from the remote MTA's.. but my problem is that the main hardware node is distributing the mail over the 120 MX nodes slowly.. I have set the SMTP_MAX_RCPTS to 5 per message for better delivery to several MTA's
That seems way too low in your configuration. You control the peers of the originating node, so a high SPMT_MAX_RCPTS should not be a problem within your network. What you need to do is make sure that the MX nodes are throttled so that they don't get blackballed by the remotes.
