This indicates that you are not doing the rate limiting on new messages
as well.

The * indicates that the subsequent deliveries were made on a single
conenction, yes.  That part is working.

By default, exim tries to immediately deliver a new message.  You want
to queue messages for this provider to prevent this.  The simplest is
probably an acl with control = queue based on some lookup (dnsdb for MX
matches some regex of their inbound MX'es is probably the simplest, but
TMTOWTDI)
