I have access to maeder.org, which is a very limited (and shared) vps at
verio, but only as a user.
I do not have access to any system log files or the mail queue. And
surprisingly enough, the first level tech support guys also had limited
access, but I think I'm talking to the right level of people now.

Thanks for the insight and confirmation of my suspicions as to what was
going on (and for giving me some good ammo for dealing with my isp).
They were able to look at my mail queue on maeder.org and make sure it was
all clear, I have no outgoing messages in the queue. They also cannot
find any indication that the was sent multiple times. But unfortunately,
another message got sent to the list while they I was on the phone with
them, so clearly the problem is not fixed.
I am now back to believing that I cannot stop the message from being sent
from my end (that's not so say that the problem is not really at
maeder.org, but I am stuck again). I really need to get in touch with
someone that can take a look at the equivalent logs and queues on the
sourceware.org side to see what is going on there.
I'm happy to have "my people" talk to "their people" in order to sort it
out if needed.
I sent mail to postmaster AT sourceware.org, as Larry suggested, but have
not heard from anyone yet.
Herb.
