Hi John, just for info, in my test server i use

dovecot_destination_recipient_limit = 1
virtual_transport = dovecot

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender}
-d ${recipient}

without any problems with users full domain layout but without local users
and postfix 2.5.5

currently testing this ( but havent looked about unwanted sideeffects yet)

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:vmail argv=/usr/bin/spamc -e
/usr/lib/dovecot/deliver -f ${sender} -d ${recipient}

evantually i will use
mailbox_command = procmail -a "$EXTENSION"
vor having an archive with local users later
