I would suggest Trillian which has a method of IMing that is native to the 
application so you can block ALL im protocols outbound and still have the use 
of IM internally without a need of a server.

Now, with that said, I have not tried it with a LARGE enterprise so while it 
works very well for a SOHO and up to a few hundred clients, I would be 
skeptical in anything larger.

If that doesnt work, look at Bluecoat which offers "reflecting" IM messaging 
and can log all IMs. The reflection takes something like MSN or Yahoo and if 
the IM is for an internal client, it's "reflected" back into the LAN but if the 
IM is for an outside client, it's blocked, dropped or otherwise stopped. Works 
very well.
