Here we go again. You actually got a Bluetooth dongle with the buggy and
crappy Zeevo TC2001 chip. They also sold it to HP for inclusion into
their iPAQs and this explain the information on the Internet. I've never
seen this problem before and it is good to be aware of it. Now all the
information seen with hcidump are making sense.

Get yourself a CSR based dongle and you won't see this problems anymore.

I actually always hit "reply all". This is a Mailman problem with using
the "Reply-To:" setting I switched to some time ago.
