And by "rate" you mean something like "number of messages per second"?
You can't configure that in exim.

The best you can do is limit the number of concurrent deliveries. But 
because exim does not have a single process responsible for delivering 
(queued) messages even that is not trivial, you need to set a few options.

Start by reading the documentations for the "remote_max_parallel". It 
pretty much explains what you need to do.

It probably also a good idea to read up on "The SMTP transport" -
http://exim.org/exim-html-current/doc/html/spec_html/ch30.html.
It's "serialize_hosts" option may interest you.

Bye,
Mark.
