SSD drives are very fast but expensive. So I have a crude idea that I'd like to see. May not be practical but would like to get some thoughts on it.
You are asking about automatic storage tiering. You can get what you want in a transparant way, independient of Dovecot. Some storage vendor (search for Fully Automated Storage Tiering - FAST from EMC or Compellent, recently bought by Dell) get what you are asking for.
If the budget is low, you can achive a "poor´s man" storage tiering with some shell scripting, cron and soft links; Or you can look at http://code.google.com/p/fscops/ for a more mature implementation. Or just use ZFS and "hybrid storage pools"
Merry Xmas
