How does one unsubscribe and subscribe to this list?

I have been to https://www.redhat.com/mailman/listinfo/fedora-list many 
many time over the last 3 weeks to change my email address.

I tried to change it. I tried to unsubscribe and re-subscribe. Everytime 
mailman promises to send a confirmation message, but I never receive it. 
I have no spam filter, so that is not it.

How else can I get this service to unsubcribe and re-subscribe me?
