This isn't really an rpm issue.  It's a difference between sendmail
and postfix.  Postfix will execute the wrapper script using the group
of the alias file where the wrapper command is defined.

Are your list aliases kept in the system-wide alias file or in a
mailman-specific alias file?  I've used the postfix integration that
is built in to mailman for ages and find that it's very convenient.

See section "6.1.1 Integrating Postfix and Mailman" in the
installation manual for complete details.  The manual is available on
FC5 at:

    /usr/share/doc/mailman-2.1.8/admin/www/mailman-install/

No need to do that.  The rpm's should work.  I've used them
successfully.
