This means the message is in the active queue, it says nothing about
connections. Messages in the active queue destined to a congested
destination wait their turn to be given to a delivery agent for
processing. Your logs show only rapid "Connection refused" errors,
show logging of deliveries that are *not* deferred due to "Connection
refused".

You present no evidence of this. If you have stuck deliveries to exchange,
debug (and post details of) the stuck connections, not the ones that
fail as a result of Exchange running out of connection slots.

The timeouts are irrelevant. Look for broken firewalls, broken path
MTU, ... report detailed facts to support *all* your anecdotal claims.
