spec.txt is your friend.


smtp_accept_max_per_host        Type: integer                      Default: 0


    This option restricts the number of simultaneous IP connections from a
    single host (strictly, from a single IP address) to the Exim daemon. Once
    the limit is reached, additional connection attempts are rejected with
    error code 421. The default value of zero imposes no limit. If this option
    is not zero, it is required that "smtp_accept_max" also be non-zero.
