For those of you that might be curious, I managed to get this done using
only postfix by taking a different approach to it. I didn't use
/etc/aliases at all (except to define the lists).

Here is the config that I used to do what I wanted.

#Sending Controls for Lists
smtpd_restriction_classes =
         may_use_lists,
         may_not_use_lists

smtpd_recipient_restrictions =
        check_sender_access hash:/etc/postfix/policy_for_senders,
        permit_mynetworks,
        permit_mx_backup,
        reject_unauth_destination,
        check_relay_domains

may_use_lists =
         permit
         #allow ANY mail

may_not_use_lists =
         check_recipient_access hash:/etc/postfix/disallowed_recipients
        permit

policy_for_senders file:

allowed_to_sendfastenal.com may_use_lists
* may_not_use_lists

disallowed_recipients file:
list1servername.fastenal.com REJECT

This config works for what I was needing...maybe I wasn't making myself
clear on what I was looking for. Now, the only question I have is what
is the ramification of having the definition of may_use_lists = permit?
  Is that going to make me an open-relay as configured?
