Yes.

exim -bP smtp_accept_max smtp_accept_max_per_host smtp_accept_reserve

smtp_accept_max defaults to 20, smtp_accept_max_per_host defaults unset.
By default, no connections (smtp_accept_reserve) are reserved for hosts
on the reserve list.

The options and how they interact are described in The Exim
Specification.
