With using the Dovecot lmtp option, where does Postfix know to refuse
email for a non-existing user or domain?  That also has to be shared?

I am trying to draw a picture in my head of all the data pieces.  Are
you saying that when using lmtp the data for Postfix and the data for
Dovecot/LMTP do not overlap anymore?  Each can have its own flatfiles?
