Based on experiences with threads 'de-muting' and a little testing,  it 
is my understanding that MM muting is dependent on IMAP keywords (i.e. 
"Raw Flags") and threading, which is reliant on the "In-Reply-To" and/or 
"References" headers (I'm not sure if both are used...) A message is 
muted if it is a thread descendant of a muted message. The muted state 
of a message is stored as the $Muted keyword. When you change the muted 
state of a message, its replies and their replies are changed 
recursively. When a message is newly seen, its place in its thread is 
determined and if it is a reply to a muted message, it gets muted.

A side-effect of this is that if you delete all members of a muted 
thread, future replies in the thread are not muted. I see this is as a 
feature, others might deem it a bug.
