When its getting a lot of spam, does it crowd out legitimate

Sometimes, but per-IP limits would be useless since the spam comes
from IPs all over the place.
Right, as I said in my correction, the EIMS limits are not per-IP but
rather three levels of connection budget: maximum total inbound SMTP
connections; connections from hosts in the OK state (passed
graylisting); connections from whitelisted hosts. So, for example,
if you have these set to, say, 20/4/2, then of the 20 total allowed
inbound connections, four are always available for OK hosts, two
connections remain always available for whitelisted hosts, and up to
16 can be consumed by hosts that you haven't classified.
