This is because there is an entry in the connection tracking table, and as 
slong as that is there the connection will be allowed by your ESTABLISHED 
rule - you would have to put the DROP rules in front of that in your FORWARD 
chain to cut off any current connections.

I have no idea how Yahoo Messenger works.   I am not the person to answer 
this question.

Right. I should have checked that.

Aren't there any servers mentioned in the messenger setup (I don't use it
myself) ?

I just checked on cs.yahoo.com and that one exists but everytime I ping that
server I'm redirected to cs41.msg.sc5.yahoo.com (216.136.233.128).
I don't know if that's the same one for you ?
