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,
