Thanks for the information Michael.  I must be configuring this 
incorrectly as the replication is not occurring when messages are being 
delivered via LMTP in my setup.  When I restart dovecot the messages are 
synced immediately, but not on delivery.

Here is my config:

# 2.2.rc2: /usr/local/etc/dovecot/dovecot.conf
# OS: Linux 2.6.32-279.22.1.el6.x86_64 x86_64 CentOS release 6.3 (Final)
