This cannot be done by Exim, since it does not process messages by size.

You might be able to hack up something external like this:
1. Use a MACRO in your configuration to specify the maximum size:
MAXSIZE=3K
2. Add a router to defer for any message greater than MAXSIZE.
3. Start queue runners manually, using -D to change MAXSIZE. You will
have to be root to do this. The sequence
exim -q
exim -q -DMAXSIZE=10M
should then achieve approximately what you want. It can only be
approximate - after all, new messages <3k can arrive at any time, and
such an arrival won't stop the second queue runner.
Untested, just an idea that I had.
Unless your large messages are really huge, however, I don't really see
the point of this. 3K is, after all, just 2 packets.
