Hi Evan,

This is a new one for us. The recent upgrade to Mailman 2.1.20 has
thrown a few curved balls.

We spinning up a new test list just now, on the server that you are on,
to confirm that it's not happening system wide.

We're also going to be testing on a few different email applications to
see if there is a problem there.

My apologies for the grief. And I hope to have a resolution in the next
couple of hours.
