dovecot - Apr 2016 - How to make quota_status policy to apply to postfix virtual aliases as well?

HelloI am setting up a postfix+dovecot setup and using quota-status service to
reject mails for full mailboxes on smtp session, according to this:
https://sys4.de/en/blog/2013/04/08/postfix-dovecot-mailbox-quota/
This is working fine and without any apparent issues. however, Postfix
doesn't seem to consult the policy when you're using virtual alias
addresses. a virtual alias, is the one that you usually define
with?virtual_alias_maps . what happens is that Postfix only verifies there is a
corresponding value for the given email address and blindly accept it. And it
seems?smtpd_recipient_restrictions , only applies to the original email address
and postfix does not consult that after applying virtual alias.
Does any one have any idea how to solve this? is there a setting that i'm
missing? or is there a better way to setup email aliases that solve this issue?

Best Regards,
