I started some of Postfix daemons with "-v" and noticed mailroutingaddress shows up on the logs when using Dovecot LDA, but not when Postfix is configured to use Cyrus lmtp socket. From this I started to think the issue is with Postfix config, this along with what you said points to exactly it: Postfix config.
I'm gonna (re)check/study the Postfix queues order and address the problem to the Postfix mailing list.
