I have no idea how to write those filters, so I can only guess ...

If I compare the entries above, I see that you put a ">"  at the end of 
the ubuntu-server entry, but there is no "<" in the same line. I don't 
know if you need both ">" and "<", but if you don't need them for the 
syntax, you should omit the ">" because there is no such character at 
the "X-BeenThere" header.

There is a "List-Id" header - maybe you can use that one instead of the
