Yahoo pager?   Good luck blocking that, as it just uses http,
proxies and all.  (Inspect script anyone?)

BTW, is it only me who considers answering a question
like this with an answer like:

        Just find whatever you did to ENABLE such
        access and undo it.

Do most firewalls have policy of whatever is not
explicitly denied is allowed?   Isn't this a FAQ?

Or has ennui and battle fatigue overtaken the
oldtimers on this list?

For ICQ, you can block access on port 4000 UDP to icq.mirabilis.com.
