Hi again,

I've write a script in perl that can query the backend and the output of the script is the using quota.
Now, the 'virtual_mailbox_limit_maps' will point to a sql db where all quota limits for all mailboxes are set. Then, with smtpd_recipient_restrictions
I'll use this option: check_policy_service unix:private/mailquota. 'mailquota' will be set up into a master.cf like this:

mailquota unix - n n - - spawn user=nobody argv=/usr/bin/perl /etc/postfix/mailquota.pl

But how can I pass to /etc/postfix/mailquota.pl the recipient argument?
The syntax to obtain the usage quota is /etc/postfix/mailquota.pl <recipient-email>.
The output is the used quota of the <recipient-email> in bytes.

Thank's a lot, bye

Simon
