Help with Postfix address mapping

[NewBlackDak]

I have Postfix setup with virtual domains, and it works fine for all the virtual domains. There's a problem though.

My domain names: mydomain.org, mydomain.com

All mail to user@mydomain.org or user@mydomain.com is accepted as long as there is a user in the DB.
Any mail to user@mail.mydomain.org, user@email.mydomain.org, user@mail.mydomain.com, or user@email.mydomain.com gets rejected.

Is there anyway to make postfix map these without adding a mail.mydomain.org domain, and aliasing all addresses?
EG
when it sees user@email.mydomain.com it's converted to user@mydomain.com, and then tries to deliver it.

Figured it out.

main.cf now has:

virtual_mailbox_domains =
mydomain.com,
mydomain.org,
mail.mydomain.com,
mail.mydomain.org,
email.mydomain.com,
email.mydomain.org

I also added these virtual domains with no mailboxes, and 1 alias apiece.
*@mail.mydomain.com = *@mydomain.com
*@mail.mydomain.org = *@mydomain.org
*@email.mydomain.com = *@mydomain.com
*@email.mydomain.org = *@mydomain.org

I'm unsure at this point wether I actually needed the virtual domains, or just an entry in the alias table. It is working fine now though, so I'll leave it alone.
