Sorry, I just forgot to comment out this line in the postfix config:
mailbox_transport·=·lmtp:unix:private/dovecot-lmtp

Now I commented it, and the messages properly have "Delivered-To: user+detail at mydomain.tld" header. But they are still dropped into the INBOX folder, so that was not the cause of the problem.
