You can do that with 'Message filters' and without using any extensions. 
Newer versions of Thunderbird (the one which comes with F16) have a 
'match all messges' filter so that for any account, you create such a  
filter to move all matching messages to the desired folder.
In older versions of thunderbird, you create a hack filter like "subject 
does not contain *#*#4765214" so that it will match practically all 
messages.
