[exim] Possible Spamassassin related feature request

Just trying the idea here before I ask for a feature request.

As we all know Exim has a spamassassin interface for testing email to
see if it's spam. I'd like to see an interface added for learning email
as spam/ham from exim. In my configuration the Exim server are separate
from the SA servers and there is yet another common server for MySQL.

Thoughts? Does this make sense?
