Hi again, I guess I don't have a clear understanding of this in the man page ?
Ran command [root@mta1 ~]# man 5 postconf default_recipient_limit (default: 20000) The default per-transport upper limit on the number of in-memory recipients. These limits take priority over the global qmgr_message_recipient_limit after the message has been assigned to the respective transports. See also default_extra_recipient_limit and qmgr_message_recipient_minimum. Use transport_recipient_limit to specify a transport-specific override, where transport is the master.cf name of the message delivery transport.
