May  5 16:22:51 posta-st-mda-v01 deliver(faccalai at posta.staging):
quota: Executing warning: /usr/local/dovecot/bin/quota-warning.sh 80
/mnt/maildir/posta.staging/USER/f/fa/faccalai at posta.staging faccalai
posta.staging

It worked!!! Thank you!

What I did is:

* recompiling a dovecot anew with support for raw storage, and deliver
(the initial one didn't have them)
* configured dovecot as per documentation (Quota 1.1, LDA, LDA/Postfix) so that:
  * it just serverd for authentication purposes (protocols = none)
  * it has a protocol lda section, with mail_plugins = quota
  * configured the auth default to create the master socket
* changed postfix's main.cf and master.cf as per documentation
* set a user's quota near the 80% limit and started testing

Thanks a lot again

Ciao
