dovecot-lda from postfix on remote dovecot server

[nik600]

Dear all

i've got many SMTP front-end that filter the mail and do some custom
stuff... then when i've decided the final destination i'd like to call

/usr/lib/dovecot/dovecot-lda to deliver the mail.

Actually i have in master.cf:

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

I'd like to know if is possible to use some other command or some
additional parameter to deliver the mail to a remote dovecot server.

Thanks
