It looks like you might have the List-Id: header wrong. It appears like this:
List-Id: A list for discussion of chirp development <developers.lists.chirpmyradio.com>
That would probably be a problem for mail-sorting programs. All of it should be on a single line.
No, actually it's fully in the definition to have multi-line headers:

Since 1982, and almost all Received headers are that way. The mail-sorting program would be at fault if it failed to properly coalesce the multiple lines before running any matching on the value.
Also, this is all generated by mailman, so you'd need to take it up with them :)
