[exim] Problem with host request ratio

We route most of our domains through a spam server when it comes to e-mails.
However, from some of our mailservers we get the following message:

12/27/07 00:35:13:515 -- (2024) server error - mail.domain.com said: The server has reached its limit for processing requests from your host. -- Please try again later. -- - message queued - sender@???

When checking the exim.conf file I find the corresponding lines that send this message. However, is there a way to get the exim server to "ignore" our spam server for the host ratio?

I know I might not make myself understood, but please let me know if you'd require more information to help.
