    RP> Well, I fix the problem with these commands:

    | 1) touch mailman/data/aliases

    | 2) postalias hash:mailman/data/aliases
    | (this command creates an aliases.db)

I think I have some better guidelines now.  I realized that
bin/genaliases can be used to initialize data/aliases.db (with a chown
afterwards).  Attached is the new README.POSTFIX instructions.  This
works for me from a virgin install, so it would be great if others
could try it out.

Hmm, I believe the key thing here is the ownership of the
data/aliases.db file, regardless of how you start Postfix.  I believe
that Postfix will always run filter programs with the same uid as the
owner of the aliases.db file, in this case user `mailman'.  Thus you
need to configure Mailman with --with-mail-gid=mailman as the
instructions now clearly state that the owner of the data/aliases*
files must be mailman.mailman.
