Ah, yes - I should have provided this info.   The list-id.identifier 
value always works.  It is the two BZ headers that start to fail.  
Apologies for leaving this out.

Yes, I've checked these, (and just checked again to be sure).. I don't 
do any customizations for list-id elsewhere.  I think that output is a 
false trail.

Nope.. nothing.

So, it must be something with the two BZ headers.  Maybe I need to write 
a parser for them?   List-id works reliably.

*Ben does more experiments*

It seems those two columns never work for new, incoming messages, but 
they always work for existing messages at startup.  Again, I am tempted 
to write a parser for them.
