How can I get a mailing list address changed?

Folks:

I recently moved my mailing list server and the address of my lists has changed.

Currently the old address works, but I want to shut the forwards down.

How can I get all @midrange.com lists changed to @lists.midrange.com?

Thanks!

I'm riding 615 miles (Yes, you read that right) in the American Diabetes 
Association's Tour de Cure to raise money for diabetes research, education, 
advocacy, and awareness.  You can make a tax-deductible donation to my ride by 
visiting https://gmane.diabetessucks.net.

You can see where my donations come from by visiting my interactive donation map

I may have diabetes, but diabetes doesn't have me!
