Hi Randy.
I do it with smtp_accept_max_per_host like this
# Restrict the number of simultaneous IP connections from a single
# host (strictly, from a single IP address). Limits for given ip
# addresses are defined in /etc/exim/max-per-host.
smtp_accept_max_per_host = ${lookup{$sender_host_address}
iplsearch{/etc/exim/max-per-host}}
And then in the max-per-host file,
# Maximum number of simultaneous connections per host
# IP address/mask max connections
127.0.0.1 20
# default
0.0.0.0/0 2
# Our IP address
# Replace the x's with your IP address
xx.xxx.xx.xxx 20
