[Mailman-Users] not getting sent out of the system. how to change?

[flyingember at 374liberty.org]

I have mailman setup in redhat 9.

I can setup a list fine through the web interface and setup users for the
list.

the registered users send email to the list email and the email gets into
the mailman system. (postfix mail log shows this)

I now have a pair of files in
/usr/local/mailman/qfiles/in
that don't leave.
I checked my cron logs and the mailman cron seems to be running.

what do I need to look at/change now?
