the problem is not posting to the list. As long as you get the CC, it's 
ok. I only meant that it is possible that you don't receive an offlist 
message, for example because some server or gateway on your side uses a 
blocklist or play "discard me" games. I've already got bounces in such 
cases (when I post via my home ISP) and this doesn't get me in a good 
mood:)

then you'll need to find such an example :)

The following seems to work for every list I've seen (by order of my 
personal preferences):

- List-Id
- List-Post
- List-Owner
- Sender
- Return-Path
- To or Cc
