It is the aliases.db file that MUST be owned (not just group) by 'mailman'. See the DELIVERY RIGHTS section in 'man local'
I changed the owner to mailman and reloaded postfix:
chown mailman:mailman /usr/local/mailman/data/aliases*
chmod g+w /usr/local/mailman/data/aliases*
postfix reload

I continue to get the same Group Mismatch error:

<mailman at box.washlaw.edu>: Command died with status 2:
    "/usr/local/mailman/mail/mailman post mailman". Command output: Group
    mismatch error.  Mailman expected the mail wrapper script to be executed as
    group "mailman", but the system's mail server executed the mail script as
    group "nobody".  Try tweaking the mail server to run the script as group
    "mailman", or re-run configure,  providing the command line option
    `--with-mail-gid=nobody'.
