yes, I can confirm this.  This is from our exim4 installation on the
list server:

it shows clearly that the exact same message with the exact same message
ID was sent to our list server 12 times.

That's really broken behaviour, and as a safety measure I strongly
recommend users of gmail accounts to refraint from further posting to
openmoko.org lists, and to take up this cause with the google mail
administrators.

As a further explanation why we didn't detect this first:
None of the OpenMoko project members notices/noticed this problemn,
since we all use cyrus-imapd which automatically discards duplicate
message-id's when delivering mails into their respective mailboxes.
