[MlMt] Mails not appearing as threads

[Charlie Clark]

Hi,

I generally have organise by thread active but some conversations aren't 
appearing as such, but the thread arc is showing them as related and in 
the conversation view, they appear as grouped by thread.

I know that threading is largely dependent upon the mail client 
preserving the right headers – in this case the "offending" MUA is 
Apple Mail – but I wonder if there's something else I should be doing 
or checking?

Thanks for your suggestions!

Charlie
