Re: Blocking Yahoo Messenger, AOL Messenger, etc.

There is an article in InfoSec magazine which covers this to some degree. Quite frankly, it's not an easy task.

Good luck.

You can try to block access for the following:

AOL - aimexpress.oscar.aol.com, login.oscar.aol.com, toc.oscar.aol.com

MSN - chat.msn.com, messenger.hotmail.com

ICQ - login.icq.com

Yahoo - chat.yahoo.com, scs-fooa.yahoo.com, scs-foob.yahoo.com, scs-fooc.yahoo.com, scs-food.yahoo.com, scs-fooe.yahoo.com, and scs-foof.yahoo.com

I am doing it for my organization at our firewall and I have at excellent results.
