This would require that the connections can be shared across smtpd server processes and to use a connection pool.
As far as i understood the source each attr_clnt/auto_clnt directly opens a connection to the remote end. (VSTREAM) Just limiting the number of connection will result in some smtpd to hold a connection for very long (max_idle, max_ttl) even if the connection is idle most of the time and other smtpd to block till a new connection is allowed? And you still need some IPC to share the number of total used connections across smtpd processes?
