Of course, you can. SMTP Callback does that very well.

If you add my patch on top:
ftp://ftp.vasoftware.com/pub/people/merlin/exim-3.31-woody-99.1/
(see README and the two diff files)

The culprit will have his mail rejected with a very explicit error:
+              sender_verify_callback_error =
+              string_sprintf("response from %s [%s] after \"MAIL FROM: <>\" was \"%s\". This does not help fight spam effectively, breaks RFCs, and prevents you from getting bounces so we can't accept mail from you",
+        host->name, host->address, big_buffer);
