J. Bakshi: > Recipient address rejected: User unknown in virtual mailbox table
You have the domain name in virtual_mailbox_domains. Postfix expects that you have the recipients in virtual_mailbox_maps. > [....] > alias_maps = hash:/etc/aliases, hash:/var/lib/mailman/data/aliases You have the addresses the local(8) aliases. Postfix uses those only for domains listed in mydestination. This is documented in http://www.postfix.org/ADDRESS_CLASS_README.html and http://www.postfix.org/VIRTUAL_README.html I suggest that you take someone's mailman instructions and follow those exactly, instead of trying to make up your own recipe.
