Hi Anoop. I'm not even close to an expert, compared to the many
knowledgeable users on this list, so I will defer to them for the real
solution. But my understanding is that you could use this in your config:
smtp_receive_timeout = 60s
Where 60s = 60 seconds.
This would allow a connection to last for 60 seconds, without any commands
taking place (again, that is my understanding)
