Hmm, utente2 became utente2/maildir/@domain.local again.
I have no experience with postfix, so I would first make sure, postfix
passes the correct values to the Dovecot LDA, by:

create wrapper script:
===== START
#!/bin/bash

( date
   echo arguments "$@"
   id
   /usr/libexec/dovecot/deliver "$@"
   rc=$?
   echo rc=$rc
   exit $rc
) >> /tmp/dovecot-lda-wrapper.$$.log 2>&1
==== END

/etc/postfix/master.cf (relevant)
# Dovecot LDA
dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/path/to/wrapper -f ${sender} -d ${recipient}

see changed argv= argument.

Then check the created log files in /tmp, if the argument of "-d" does or
does not contain the "/maildir/" part.

If it does, you will have to check your postfix installation, when the
recipient string gets changed.  Maybe your postfix was configured to
deliver to Maildirs directly before and therefore at some point the
"/maildir/" is added.
