That was my first thought and is usually the case. But after
a growing number of people have complained I believe it is a
problem with the listserver.
I checked their email addresses and they "were" subscribed
under them in July. They later unsubscribed from the list but
are still getting mail. Some have returned headers.
One of the addresses is an account of mine, I unsubscribed it
and am 'no longer on the list' but it is still getting mail sent
to that address.
