Done, but I had to do answer (-->):

Hmm... Looks like a unified diff to me...

Dovecot v2.2.7 (87ff0023fe79+) starting up. And I can confirm, that again, no status=undeliverable show up.

Where 1) failed (except with warn_if_reject), but 2) succeeded? Where both were basically doing the same thing, except I suppose with some actual difference. Or were the mails really not delivered via LMTP but something else?
I am not sure, if I do understand you correctly. My setup is:
postfix smtpd
dovecot/lmtp user authentication
postfix --> amavisd
amavisd/lmtp --> postfix
final deliver by dovecot/lmtp
