[Exim] Allowing more INBOUND SMTP connections

I'm running into a small problem here lately...that is I'm seeing this
in my logs:

2001-10-30 20:28:46 Connection from 198.178.8.81 refused: too many
connections
2001-10-30 20:28:47 Connection from 208.35.9.135 refused: too many
connections
2001-10-30 20:28:52 Connection from 63.251.31.40 refused: too many
connections
2001-10-30 20:28:53 Connection from 192.219.17.122 refused: too many
connections

How can I allow exim to permit more INBOUND connections?? Would
increasing the remoye_max_parallel from 20 to 40 help any? Or is there
a better setting to play with??

Thanks,

George
