To clarify - I see this message after EVERY message reception.  My last 
log section is:

Everything looks clean - except that lmtp disconnect message.  It may 
not be an error - or a warning - but it looks like one.  If I need to 
change my configuration in either Postfix or Dovecot to "fix" it - 
please tell me so.  Otherwise, if the message just read "Disconnect from 
local" to match with the initial connect it would be fine.  But as it is 
- it leaves me feeling I've got something setup wrong.

And indeed - do I?  In Postfix, I've simply set my transport to use the 
lmtp via unix socket.  I have NOT set a destination_recipient_limit - as 
I didn't think I needed to do so, unlike when use the lda via pipe.  I 
had lmtp timeouts, so I set process_min_avail=5.
