I did try something like this, which didnt make a difference:

queue_only
queue_only_load = 10
queue_run_max = 10
(not all at once)

This is printed instantly:
.........
listening on port 25...
host in rfc1413_hosts? yes (*)

It waits here for some time then does this:

Process 9999 is handling incoming connection from [999.999.999.999]
host in host_lookup? no (option unset)
host in host_reject? no (option unset)
host in host_reject_recipients? no (option unset)
host in auth_hosts? no (option unset)
host in sender_unqualified_hosts? no (option unset)
host in receiver_unqualified_hosts? no (option unset)
host in helo_verify? no (option unset)
host in helo_accept_junk_hosts? no (option unset)
