Muraoka-san,

That is normal behavior if you addressed your original post to both <[log in to unmask]> and <[log in to unmask]>.  The first address is the correct one.  The second address is in the Reply-To header of all messages from the list but it is defunct, so all messages sent to the second address are returned as undeliverable.
