The only obvious thing I can see wrong there is that you have

    mail_plugins = " sieve"

in dovecot.conf, which should be

    mail_plugins = sieve

but I don't know that that would prevent delivery.

Is Postfix deferring the message, or does it think it's been delivered?
What do you see in your logs when a message is delivered (since you've
redirected Dovecot away from syslog, you'd need to look at both
Postfix's and Dovecot's logs)?

What happens if you feed a message to dovecot-lda manually, as
'mailman'? Check the exitcode of lda and the logs, as well as seeing if
the message was delivered.

Since you've set up a dedicated transport for Dovecot, it would probably
be worth using LMTP instead of the LDA. It should be more efficient, and
since you're only using a single virtual user you can tell dovecot to
run the LMTP server as 'mailman' instead of root.
