Ah, in that case that's just because some people are literally sending a
message to the list twice under its old and new addresses.  They
generally seem to be in portions of threads originating with Brian.

I think what's happening is that people still send to
parted-devel at lists.alioth.debian.org rather than
parted-devel at alioth-lists.debian.net for any of various likely reasons,
and then when Brian replies their mailer picks up something like the
List-Post header and adds that too.  I don't know whether it's possible
to do much about this unless Brian can work out how to make their mailer
pick just one of the two list addresses and stick to it.
