Yes, the in-reply-to and references headers are needed to establish 
parent-child relations but subject selection must be applied first. 
Eudora (at least pre-6) shows a single-level list, so these relations 
are not visible anyway. This is why I wrote 'grouping' not 
'threading'. For most lists, I find this quite sufficient. Others may 
be more demanding :)
