How do you allow postfix subdomain mail delivery?

    I have multiple servers on my network receiving emails, and each one is set to receive messages at domain.com, mail.domain.com, and mx?.domain.com (currently running mx1 and mx2; the new ispconfig3 server is designated mx4). Server is Ubuntu, SMTP is postfix. Incoming emails generate the following log:

    Note that the mailbox [email protected] has been created and will accept emails. So this is a two-part question, and I'm hoping there is an easy answer...
    1. A way to tell ispconfig that emails to [email protected] will also be accepted at [email protected]
    2. A method of designating that this particular server will also accept emails to all virtual domains that are tagged with this server's mx -- thus emails received for [email protected] and [email protected] would also be accepted.
    Question #1 is the most important part I am focusing on, since #2 can be worked around with an easy solution to #1. I can post my config files if needed, but I don't believe this is a configuration issue. Postfix seems to be working as instructed (only allowing emails to known addresses), I just can't figure out how instruct it to allow the subdomain aliases.

    Add mx4.domain.com as email domain in ISPConfig and then add email addresses or aliases for the domain mx4.domain.com

    So I'm just supposed to create a copy of every user's mailbox for every mx subdomain (and yes, there are reasons why the emails will get the mx tacked onto the address)? Assuming I were to do this, how then do you propose I get all of the received emails back into a single mailbox for the user to read?

    I've been using LDAP records for years. Under postfix, I have a query that picks up associatedDomain values for each domain, then allows emails for all users under this domain to also come in under the addition domains or subdomains. I was really hoping to find something straightforward like this to easily expand on the accepted subdomains of all users under a given domain.
