There is no standard/defined "important" IMAP flag/keyword.   
Thunderbird is most likely using the X-Priority pseudo-standard header  
in the message itself (which makes sense: it is the sender's intention  
of the message's importance which should be displayed, not the  
receiver's.  Objections to this reasoning by some is likely the reason  
the header has never been standardized).
